Slide 2: Present era of nanotechnology-complex machines
Medical nanodevice , a micron-scale robot assembled from nanoscale parts.
These nanorobots can work together in response to environment stimuli and programmed principles. Slide 3: Construction and design of Nanorobots Nonorobots design derived from biological models
Various components include onboard sensors, motors, manipulators, power supplies, and molecular computers
The best-known biological example- ribosome ,used to construct robotic arm
The manipulator arm driven by detailed sequence of control signals
Control Signals are received by robotic arm via onboard sensor using broadcast architecture
Assemblers are molecular machine systems performs molecular manufacturing at the atomic scale Slide 4: Recognition of Target Site by Nanorobots In the 3D workspace the target has surface chemicals
Manufacturing better sensors and actuators - Nanorobot Control Design (NCD) simulator
The nanorobots’ small Brownian motions to find the target by random search
They monitor for chemical concentration significantly above the background level
Nanorobots at the target release another chemical, which others use as an additional guiding signal to the target. Slide 5: Medicinal Applications Breaking up blood clots: Nanorobots could travel to a clot and break it up.
Fighting cancer: The robots could either attack tumors directly using lasers, microwaves or ultrasonic signals or delivering medication directly to the cancer site.
Helping the body clot: One particular kind of nanorobot is the clottocyte, or artificial platelet.
Parasite Removal: Nanorobots could wage micro-war on bacteria and small parasitic organisms inside a patient.
Gout: Gout is a condition where the kidneys lose the ability to remove waste from the breakdown of fats from the bloodstream. A nanorobot could break up the crystalline structures at the joints, providing relief from the symptoms,
Breaking up kidney stones: A nanorobot could break up a kidney stones using a small laser. Slide 6: Nanorobot The robot swims through the arteries and veins using a pair of tail appendages. Slide 7: Robotic Laproscopy Laparoscopy has some different robotic systems
Example-Davinci surgical system
Basic principle-control of 3 or 4 robotic arms by a surgeon.
A Surgeon Console
Patient side cart
An image processing stack
Nanorobots Slide 8: Implementation of nanorobot Real time 3d prototyping and simulation
50 nanorobots detect and act on targeted area
The target area is mixed with RBC’s
Nanorobots communicate through electromagnetic ultrasound transducers
Effectively identifies and destroys the targeted tumour area. Slide 9: The time required for nanorobots to achieve the
targets in vessels with different diameters. Slide 10: Nanorobot destroying cancerous cells Slide 11: Future of nanorobots Maintain tissue oxygenation
Monitoring nutrient concentrations in the human body
Assist inflammatory cells (or white cells) in leaving blood vessels to repair injured tissues.
Deliver anti-HIV drugs
Curing skin diseases Slide 12: Conclusion The development of nanorobots may provide
remarkable advances for surgery and treatment of
Nanorobots applied to medicine hold a wealth of promise from eradicating disease to reversing the aging process.
One day have thousands of microscopic robots rushing around in our veins, making corrections and healing our cuts, bruises and illnesses.
With nanotechnology, it seems like anything is possible. PREPARED BY : PREPARED BY DHIVYA.P
