1. Compare and contrast Nanoscience from Nanotechnology. Point out your bases of
comparisons.

Nanoscience focuses on the study of phenomena and properties at the nanoscale, while
nanotechnology applies this knowledge to solve practical problems. Nanoscience emphasizes
understanding the fundamental behavior and interactions of nanoscale materials, often involving
theoretical and experimental approaches. It integrates disciplines such as physics, chemistry,
biology, and materials science to uncover nanoscale properties and interactions. In contrast,
nanotechnology is concerned with the engineering, design, and development of tools and
products, aiming to manufacture and manipulate materials at the nanoscale. It draws from fields
like engineering, IT, and medicine to create tangible solutions. While nanoscience provides
insights and models of nanoscale phenomena, nanotechnology translates these findings into
practical innovations, such as using nanoparticles for drug delivery. Together, they represent the
interplay between theoretical understanding and practical application in the nanoscale domain
(Bayda et al., 2019).

The United States Environmental Protection Agency (EPA) classifies nanomaterials into
several categories based on their properties, structure, and potential environmental or health
risks. These categories are aimed at assessing the safety of nanomaterials and guiding regulatory
decisions. Below are the primary categories of nanomaterials according to the EPA, along with a
discussion of each:

1. Nanoparticles

Nanoparticles are materials with at least one dimension in the range of 1 to 100
nanometers (nm). These materials are widely used across various industries and applications,
including medicine, electronics, and consumer goods. Nanoparticles can be composed of metals,
polymers, carbon, or other materials, and can exist in a variety of shapes, including spherical,
rod-like, or irregular (EPA, 2017).

Applications: They are commonly used in products such as sunscreens, cosmetics, food
packaging, and medical drug delivery systems (Oberdörster et al., 2005).

Environmental and Health Concerns: Because of their small size, nanoparticles may
penetrate biological membranes, leading to potential toxicity. For instance, inhaled nanoparticles
could cause respiratory issues, while others might accumulate in organs like the liver or kidneys
(Oberdörster et al., 2005; Oberdörster, 2000).

Evidence: Studies have shown that nanoparticles, such as titanium dioxide and zinc oxide
(commonly used in sunscreens), may pose risks to aquatic organisms (Nel et al., 2006).

2. Nanotubes
 Nanotubes are hollow, cylindrical nanostructures with diameters in the nanometer range
and lengths that can span several micrometers. Carbon nanotubes (CNTs) are the most well-
known type, but nanotubes can also be made from materials like boron nitride and silicon (EPA,
2017).

Applications: CNTs are used in electronics, energy storage, and drug delivery systems
due to their high strength and electrical conductivity (De Volder et al., 2013).

(MWCNTs) resulted in pulmonary inflammation and fibrosis in rats.

3. Nanofibers

Nanofibers are fibers with a diameter of 1 to 100 nm, with lengths extending to micrometer
or even millimeter scales. These fibers can be composed of a wide range of materials, including
metals, polymers, and ceramics (EPA, 2017).

Applications: Nanofibers are used in filtration systems, medical implants, sensors, and
reinforced composite materials (Choi et al., 2007).

Environmental and Health Concerns: Nanofibers, particularly carbon-based ones, may

pose inhalation risks similar to those of nanotubes due to their fibrous structure. Prolonged
exposure to certain nanofibers could potentially lead to lung inflammation or other respiratory
issues (Colvin, 2003).

Evidence: Research on inhalation exposure to nanofibers has shown that they may induce
pulmonary inflammation and could cause more severe toxicological effects compared to larger
fibers (Kermanizadeh et al., 2014).

4. Nanowires

Nanowires are one-dimensional nanomaterials with a diameter in the range of 1 to 100

nm and lengths that can extend to several micrometers or even millimeters. They can be
composed of metals, semiconductors, or carbon (EPA, 2017).
 Applications: Nanowires are used in the development of next-generation electronic
devices, energy storage systems, and sensors (Zhou et al., 2007).

Environmental and Health Concerns: Nanowires may present similar toxicity concerns as
other nanomaterials, including the risk of inhalation and potential accumulation in biological
tissues. Their long, thin structures may also pose unique challenges in terms of environmental
dispersion and toxicity (EPA, 2017).

Evidence: A study by Nagy et al. (2014) demonstrated that metallic nanowires can induce
toxicity in human cells, raising concerns about their environmental and health impacts.

5. Nanoplates

Nanoplates are thin, flat nanostructures with one dimension much smaller than the other
two, typically ranging from 1 to 100 nm in thickness. They can be composed of various materials,
including metals, ceramics, and carbon-based substances (EPA, 2017).

Applications: Nanoplates are used in electronic devices, sensors, and as catalysts (EPA,
2017).

Environmental and Health Concerns: Due to their large surface area and increased
reactivity, nanoplates may pose environmental risks, particularly in terms of their potential for
chemical reactivity and toxicity (EPA, 2017).

Evidence: Research on the toxicity of metal oxide nanoplates, such as titanium dioxide
and cerium oxide, has shown potential for oxidative stress and toxicity in aquatic and mammalian
models (Mao et al., 2013).

6. Quantum Dots

Quantum dots are semiconductor nanomaterials that exhibit unique optical properties due
to their small size and quantum mechanical effects. These particles typically range from 1 to 10
nm in diameter (EPA, 2017).

Applications: Quantum dots are used in solar cells, LED displays, and medical imaging
(Bruchez et al., 1998).

Environmental and Health Concerns: Quantum dots can contain toxic metals such as
cadmium, which raises concerns about their environmental and human health impacts. If released
into the environment or incorporated into food products, quantum dots may pose significant risks
(EPA, 2017).

Evidence: Studies have shown that the release of cadmium-containing quantum dots
could lead to toxic effects in aquatic organisms and may pose risks to human health if they are
ingested or inhaled (Liu et al., 2007).

7. Nanocomposites

Nanocomposites are materials that incorporate nanomaterials into a matrix to enhance

their properties, such as strength, electrical conductivity, or reactivity. These can be made from
polymers, metals, or ceramics (EPA, 2017).

Applications: Nanocomposites are used in a wide range of industries, including

automotive, construction, and packaging, where they enhance the mechanical and thermal
properties of materials (Gojny et al., 2005).

Environmental and Health Concerns: While nanocomposites can provide improved

material properties, the release of free nanoparticles from composites over time could lead to
environmental exposure, particularly through waste disposal or degradation processes (EPA,
2017).

Evidence: Studies have demonstrated that certain nanocomposites, such as those

containing carbon nanotubes or silver nanoparticles, may release nanoparticles into the
environment, potentially causing toxic effects (Kim et al., 2010).

8. Nanocoatings

Nanocoatings are thin layers of nanomaterials applied to surfaces to enhance properties

like water resistance, UV protection, or antimicrobial effects. These coatings typically involve
nanoparticles embedded in a matrix material (EPA, 2017).

Applications: Nanocoatings are found in products like textiles, medical devices, and
electronics (Schmidt et al., 2009).

Environmental and Health Concerns: As with other nanomaterials, nanocoatings can

release nanoparticles into the environment over time, raising concerns about their long-term
effects on ecosystems and human health (EPA, 2017).
 Evidence: Research has shown that the release of nanoparticles from nanocoatings can
lead to exposure in aquatic systems and pose risks to aquatic life (Ravichandran et al., 2017).

The EPA categorizes nanomaterials to help guide risk assessments and regulatory actions.
Each category of nanomaterials, from nanoparticles to nanocomposites, has distinct properties
and applications, but all share potential concerns regarding their environmental and health
impacts. Continued research and regulation are essential to ensure that the benefits of
nanotechnology are realized while minimizing potential risks (EPA, 2017; Oberdörster et al.,
2005).

10. What are the properties of nanomaterials? Name 10 properties and describe each.
What kind of microscopes are being used?

Nanomaterials, due to their extremely small size (typically in the range of 1 to 100 nanometers),
exhibit unique properties that differ significantly from bulk materials. These properties arise from
quantum effects, high surface area, and increased reactivity at the nanoscale. Below are 10
properties of nanomaterials, each discussed with supporting evidence and references:

1. Increased Surface Area to Volume Ratio

• Description: As nanomaterials are scaled down to the nanoscale, the surface area-to-
volume ratio increases dramatically. This means that a larger proportion of atoms or
molecules are exposed at the surface, enhancing their reactivity and interaction with the
environment.

• Implications: This property makes nanomaterials more reactive than bulk materials, which
is beneficial for applications such as catalysts, sensors, and drug delivery systems
(Bhushan, 2017).

• Evidence: For example, the surface area of gold nanoparticles increases significantly with
their size reduction, making them more effective in catalytic reactions (Saha et al., 2008).

2. Quantum Effects

• Description: At the nanoscale, the electronic properties of materials can be governed by

quantum mechanics. Electrons in nanomaterials may behave differently from those in bulk
 materials due to quantum confinement, where electrons are restricted in motion due to the
small size of the material.

• Implications: These effects can result in unique optical, electronic, and magnetic
properties, such as changes in absorption spectra, conductivity, and the ability to emit light
(quantum dots).

• Evidence: Quantum dots, which are semiconductor nanoparticles, exhibit size-dependent

fluorescence, where their emission color changes based on their size (Alivisatos, 1996).

3. High Strength and Hardness

• Description: Nanomaterials often exhibit superior mechanical properties, such as

increased strength and hardness, compared to their bulk counterparts. This is because of
the reduced number of defects at the nanoscale and the increased bonding strength
between atoms.

• Implications: Nanocomposites, for instance, can be much stronger and lighter than
conventional materials, making them ideal for applications in aerospace, automotive, and
construction (Liu et al., 2010).

• Evidence: A study by Ruan et al. (2007) demonstrated that nanostructured metals, such
as nanocrystalline copper, exhibit significantly higher strength than their coarse-grained
counterparts.

4. Optical Properties (Plasmonics)

• Description: Nanomaterials can exhibit unique optical properties, including surface

plasmon resonance (SPR). This occurs when conduction electrons on the surface of
nanoparticles (such as gold or silver) resonate with incident light.

• Implications: SPR is used in a variety of applications, including biosensors, imaging, and

photothermal therapy. The color and brightness of gold nanoparticles, for example, can
change depending on their size and shape (Link & El-Sayed, 2003).

• Evidence: The plasmonic properties of gold nanoparticles have been exploited in

biosensing applications to detect specific molecules (Jain et al., 2006).

5. Magnetic Properties
 • Description: Nanomaterials exhibit unique magnetic properties due to their small size and
high surface area. Magnetic nanoparticles, such as iron oxide nanoparticles, can have
superparamagnetic properties, where they exhibit magnetic behavior only in the presence
of a magnetic field.

• Implications: This is useful in medical imaging (MRI), targeted drug delivery, and data
storage (Gao et al., 2005).

• Evidence: Superparamagnetic iron oxide nanoparticles (SPIONs) are widely used in

biomedical applications, including as contrast agents for MRI (Gao et al., 2005).

6. Electrical Conductivity

• Description: Many nanomaterials, particularly carbon-based nanostructures like carbon

nanotubes (CNTs) and graphene, exhibit enhanced electrical conductivity. This is due to
the unique electronic properties at the nanoscale.

• Implications: These materials are used in applications such as flexible electronics,

conductive inks, and energy storage devices (Novoselov et al., 2004).

• Evidence: Graphene, a one-atom-thick sheet of carbon atoms, is known for its

extraordinary electrical conductivity, even surpassing copper in some configurations
(Novoselov et al., 2004).

7. Thermal Conductivity

• Description: Nanomaterials can exhibit different thermal conductivity than bulk materials.
Some nanomaterials, such as carbon nanotubes, have very high thermal conductivity,
while others, like aerogels, can act as excellent thermal insulators.

• Implications: Nanomaterials are used in applications requiring thermal management, such

as in electronics, aerospace, and construction (Choi et al., 2008).

• Evidence: Carbon nanotubes have been found to have excellent thermal conductivity,
which makes them ideal for heat dissipation in electronic devices (Keblinski et al., 2002).

8. Self-Assembly

• Description: Many nanomaterials can spontaneously organize into ordered structures

without the need for external guidance. This process, called self-assembly, is driven by
 interactions at the molecular level, such as van der Waals forces, hydrogen bonds, or
electrostatic interactions.

• Implications: Self-assembled nanomaterials are used in drug delivery systems, sensors,

and nanostructured surfaces for various applications (Whitesides et al., 2002).

• Evidence: Researchers have demonstrated that nanoparticles can self-assemble into

complex structures, such as films or nanoparticle clusters, for applications in catalysis
(Zhang et al., 2007).

9. Catalytic Properties

• Description: Nanomaterials are highly effective catalysts due to their increased surface
area and the ability to interact more readily with reactants. The high surface-to-volume
ratio allows for more active sites, making reactions faster and more efficient.

• Implications: Nanocatalysts are used in a wide range of chemical processes, including

environmental remediation, energy production, and chemical manufacturing (Hernandez
et al., 2014).

• Evidence: Gold nanoparticles, for example, have been shown to catalyze reactions such
as the oxidation of carbon monoxide (Haruta, 2007).

10. Biocompatibility

• Description: Many nanomaterials are highly biocompatible, meaning they can interact with
biological systems without causing harm. This property is especially important for
biomedical applications, such as drug delivery, tissue engineering, and diagnostic
imaging.

• Implications: Biocompatible nanomaterials are used in medical devices, drug delivery

systems, and imaging technologies (Wang et al., 2012).

• Evidence: Gold nanoparticles, for instance, have been widely used in biomedical
applications due to their biocompatibility and ease of functionalization (Jain et al., 2006).

and vehicles. Nanocomposite materials provide stronger, lighter, and more flexible armor
solutions. Evidence: Nanomaterials such as CNTs and graphene are used to create body armor
that is stronger than traditional materials while maintaining mobility and comfort (Singh et al.,
2014).

13. Military: Nano-enabled Sensors

Application: Nanotechnology is used to develop advanced sensors for military applications,

including detection of chemical, biological, and radiological threats. Evidence: Nanosensors are
being developed for rapid, real-time detection of toxic agents or explosives, improving the ability
of military forces to respond to threats (Sun et al., 2007).

14. Military: Nano-enabled Drugs and Vaccines

Application: Nanotechnology enables the development of drugs and vaccines that can be
precisely delivered to targets within the body, improving effectiveness and reducing side effects.
Evidence: Nano-carriers are used to deliver therapeutics in a controlled manner, targeting specific
tissues or pathogens, enhancing the effectiveness of medical treatments for soldiers in combat
(Mansouri et al., 2016).

15. Military: Stealth Technology

Application: Nanotechnology is used to improve stealth technology in military

aircraft and vehicles. Nanomaterials are designed to reduce radar visibility by absorbing or
scattering electromagnetic waves. Evidence: Nanocoatings and composites can be used to
develop radar-absorbing materials, which make military vehicles and aircraft less detectable by
enemy radar systems (Jin et al., 2014).
