Nanotechnology
 The word nanotechnology popularized by the K Eric Drexler in 1980.
 Nanotechnology (sometimes shortened to "nanotech") is the study of manipulating matter on an atomic
and molecular scale.
 It works with materials, devices and other structures with at least one dimension sized from 1 to 100
nanometers.
 With a variety of potential applications, nanotechnology is a key technology for the future.
 Two categories of nanotechnology
 Strong nanotechnology: It focuses on the general-purpose assembler: a microrobot that, with the proper
programming, can build anything.
 Weak nanotechnology: It is anything up to "strong," including the manipulation of matter at the atomic
level 8/20/2015

Nanorobotics
 Nanorobotics is the technology of creating machines or robots at or close to the microscopic scale of a
nanometre.
 Nanorobotics is the tiny machine designed to perform a specific task whose components are at or close
to the scale of a nanometer.
 The main element used will be carbon in the form of diamond nanocomposites because of the strength
and chemical inertness of these forms.
 Programmable assembly of nm-scale components either by manipulation with macro or micro devices,
or by directed self-assembly.
 Design and fabrication of robots with overall dimensions at or below the mm range and made of nm-
scale components.
 Programming and coordination of large numbers (swarms) of such nanorobots.
 The best example of this technology is Nanorobot. 8/20/2015

Nanorobot
 Nanorobot also called as Nanobots , Nonoids, Nanites , Nanomachines or Nanomites.
 Nanorobot is the part of nanotechnology that performs task at nanoscale dimensions.
 A Nanorobot is a nanotechnological robot machine which is a mechanical or eletromechanical device or
microscopic devices whose dimensions are measured in nanometres.
 Nanorobots are molecular machine or tiny machines used to cure diseases in human or in any organism.
 Nanorobots would typically be devices ranging in size from 0.1-10 micrometres.
 Nanorobot is one of the most advanced forms of nano-medicine.
 The first useful applications of nanomachines might be in medical technology, which could be used to
identify and destroy cancer cells.

Types of Making Nanorobots
1. Nubots:
 The first approach is through nubots. Nubot is an abbreviation for ‘nucleic acid robots.’ Nubots are
organic molecular machines at the nanoscale. DNA structure can provide means to assemble 2D and 3D
nanomechanical devices.
2. Bacteria based:
 This approach proposes the use of biological microorganisms, like the bacterium E(Escherichia)- coli.
Thus the model uses a flagellum for propulsion purposes. The uses of electromagnetic fields are normally
applied to control the motion of this kind of biological integrated device.

Injection
 Nanorobots are introduced into the body by surgery.
 So the nanorobots are made smaller than the blood vessels as it can travel.
 The nanorobot is injected in femoral artery
8/20/2015
33

Navigation & Positioning
 Nanorobots use blood flow for its movement.
 All nanorobots communicates outside with Ad-Hoc Network.
 To know the location of nanorobots where it goes we use ultrasonic technique
 Signal processing techniques are used to track this ultrasonic signal
 Nanorobots movement depend upon
 Speed of blood
 Get through the heart without stuck
 React with changes in blood flow rate
 Able to change the direction according to the blood stream
 To satisfy this, nanorobots should be made with electric motors to turn propeller.
