NANOROBOTICS

INTRODUCTION

 The possibility of nanorobots was first proosed by ‘Richard Feyman’ in


his talk” There’s plenty of Room at the Bottom”in 1959.
 Robotics is the use of technology to design and manufacture (intelligent)
machines, built for specific purposes,programmed to perform specific
tasks.
 Generally nanotechnology deals with size ranging from 1 to 100
nanometer.
 Nanorobots are nanodevices that will be used for the purpose of
maintaining and protecting the human body against pathogens.
 Nanotechnology is the engineering of functional systems at the molecular
scale. This covers both current work and concepts that are more
advanced.
 In its original sense, nanotechnology refers to the projected ability to
construct items from the bottom up, using techniques and tools being
developed today to make complete, high performance products.

WHAT IS NANOROBOTS?

 Nanorobots are theoretical microscopic devices measured on the scale of


nanometer ( 1mn equals one millionth of 1 millimeter).
 Nanorobots are tiny machines used to cure diseases in human or in any
organism.
 Performs task at nanoscale dimensions.
 The prefix ‘nano’ means billionth.
 They would work at the atomic,molecular and cellular level to perform in
both the medical and industrial fields.
 These are very sensitive to the acoustic signal.
 These nanorobots can be programmed using the sound waves to perform
the specified tasks.
 These nanorobots identify the particular harmful cells and tey to
quarantine it.

WORKING OF NANOROBOTS

When an implantation of tiny robots into our blood stream. The robots
detects the cause of the fever, travels to the appropriate system and
provides a dose of medication directly to the infected area.

ELEMENTS

 Carbon is the principal element comprising the bulk of a medical


nanorobots, probably in the form of diamond or diamondoid
nanocomposites.
 Many other light elements such as hydrogen, sulfur, oxygen, nitrogen,
fluorine, Silicon, etc. will be used for special purposes in nanoscale gears
and other components.

MECHANISM

 The attached bacteria by rotating their flagella push the microscope to


forward by using different chemicals the on/off motions of microrobots
are controlle.
 These chemicals bind to the flagella motor an restrict their movement.
 Mainly used chemical are EDTA and copper ions are used to stop their
motion and EDTA(ethylene demine tetra acetic acid)used to restart their
motion.
 The swimming robots contains robotic body, poly styrene microspheres,
which are also called as micro beads.

THE ATTACHMENT TAKES PLACE IN 2 STEPS:-


 Reversible-> In reversible attachment the bacteria adhere the micro bead
with vanderwalls,acid-base interactions and electrostatic forces. These are
weaker bonds hence this attachment is reversible
 Irreversible-> Irreversible attached to them by forming strong bonds.

WHY IN THE MEDICAL FIELD


 The manufacturing technology of the 21st centry.
 Computer controlled molecular tools much smaller than a human cell and
built which accuracy and precision of drug molecules.
 Such tools will medicine,for the first time,intervene in a sophisticated and
controlled way at the cellular and molecular level.
 They remove obstructions in the circulatory system,kill cancer cells, or
take over the function of sub cellular organelles.
 Just as today we have the artificial heart, so in the future we colud have
the artificial mitochondrion.

RESPIROCYTE

 Artificial Red Blood Cells


 Enough for 36 hours of oxygen at rest
 Spacewalks,Deep sea diving
 Built of 18billion precisely arranged structural atmos
 Exchange gasses via molecular sorting rotors

HEART SURGERY

 Blood vessels play an important role in suppling blood to all parts of our
body.
 Due to the fatty deposition on the walls of blood vessels blood will not
move freely to all parts.
 These leads to heart attacks and damage the vital organs.
 Molecular sorting rotors:
 Made up of carbon nanotubes.
 Sheet of carbon atom form a carbon nanotubes.
 SWNT’s can be used to generate mechanical
 Nanotube with nanogears used for changing the direction of movement.

CANCER TREATMENT
 Delivers radiation directly to the tumor cells in the liver using
microsphere.The size of microsphere is 20-30um in diameter.
 It has currently been used in the U.S., Canada and Australia.
 Targeted-delivery of pharmaceutical agents to specific cellular and
intracellular destinations within the human body.
 Could be a very helpful and hopeful for the therapy of patients, since
current treatments like radiation therapy and chemotherapy often end up
destroying more healthy cells than cancerous ones.
 It provides a non-depressed therapy for cancer patients.

Controlling glucose level using nanorobots


 The nanorobot can be programmed to activate sensors and measure
regularly the BGLs early in the morning, before the expected breakfast
time.

NANOROBOTICS

 The nanorobot is programmed also to emit a signal on specified lunch


times, and to measure the glucose levels in desired intervals of time.

BREAKING UP OF KIDNEY STONES


 Kidney stones can be intensely painful.
 The larger the stone the more difficult it is to pass.
 Doctors break up large kidney stones using ultrasonic frequencies, but it
is not always effective.
 A nanorobot could break up a kidney stones using a small laser.

ADVANTAGES
 Small Size
 Inexpensive
 No maintenance
 Automated
 Painless Treatment

 -Fully eliminate pathogens and viruses in minutes


compared to weeks or months
 -Greatly reduces need for doctors, drug companies,
healthcare, etc.
 Extending Lifespan
 Using nano-fabrication and self-assembly,
 Clean out any other toxins and undegradable material that naturally
remains in cells,contributing to agine

CONCLUSIONS
 From these type of inventions, it will be useful for man to cure many
diseased then lead a fantastic life.
 We can use the technology for more accuracy in any field.
 Nanorobots are going to revolutionize in medical industries in future.
 All safety concerns must be addressed on an individual basis
