NANOTECHNOLOGY. Nano in real world Nanotechnology in medicine PRESENTED BY: PRESENTED BY: B.SUMAN NAIDU & K.R.YELLU KUMAR B.SUMAN NAIDU & K.R.YELLU KUMAR 4/4 MECH,INTELL ENGINEERING COLLEGE

Nano technology is nothing but combination of engineering and chemistry Nano technology is nothing but combination of engineering and chemistry Atoms are the building blocks of the matter Atoms are the building blocks of the matter 1/80000th the size of human hair 1/80000th the size of human hair BASIC FACTS ABOUT NANOTECHNOLOGY:

Basics to produce any Nano products We must be able to manipulate or replace the individual atoms. We must be able to manipulate or replace the individual atoms. To replace the individual atoms a nano scopic machine is used called the Assembler. To replace the individual atoms a nano scopic machine is used called the Assembler. The combination of assemblers is called Replicators. The combination of assemblers is called Replicators.

Types of nano materials

CARBON NANOTUBES (Key role in Nano Technology): In 1991, carbon nanotube was discovered from the cathode product in carbon-arc discharge method. In 1991, carbon nanotube was discovered from the cathode product in carbon-arc discharge method.

Nano medicine a pill-size video camera DNA testing This video camera uses a miniature CMOS video imaging chip and white LED as a light source. DNA could be coated with silver and made to conduct electricity. They predicted that the ability of DNA to organize itself into complex patterns and copy these patterns precisely over again and again would render such life molecules to develop into electronic molecules.

molecular manufacturing systems In molecular manufacturing systems, using nanotechnology it is possible transform raw materials, in molecular form, into finished products. Impurities could be separated from feedstock molecules using a sorting rotor which can be seen as in the figure.

Nano power generator Below figures shows the possibility for the production of compact power generation using nanotubes which are very productive even from the commercial side.

Electronic display by using nano Nano technology is also playing an important role for electronic displays so as replace existing CRO and CRT’s and it is even competing with LCD (Liquid Crystal Display) which is the advanced trend in electronic displays.
