Definition of nano technology Nano shell Nano particles Carbon nano tubes &its application. Application of nano technology

What’s Nano technology?.. is a science that deals with the study, control, development and alteration of structures of less than 100 nanometers (one nanometer is a billionth of a meter;

Nano technology may able to create many new materials with a vast range of applications such as in medicine,electronics,biomaterials& energy production.

Nano scale**

Making a material Nano scale change its melting point &physical properties

The perfix nano means one bilionth1nm=10-9 meter . 80.000 nano particles

in a raw are the width of a human hair

Formation of Nano shells

Preparation :coper,silver salts ,oxides put together &heated to 6000c

Deep Dish, Spain ZnO coated glass, TiO2 in paints.

scanning electron micrograph shows a carbon nanotube sheet pic2**/.An artificial muscle made from a sheet of these carbon

Application of nano technology1- In medicine a-binding 5-fu drug to

the CU (drug delivery) Pill camera has video

chip& lab system ship

1- in medicine

B- nano material for making creams to treat skin

They use (ZnO) as a nano particle why?

1. Block u.v light

2. Appear clear

Nano tubes based sensor that detect bacteria in drinking water, then happen treatment

Future possibilities

Artificial white blood cells Encapsulation of transplanted islet cells

protect them from external environment &rejection by the body

-Encapsulate biologically active materials such as enzymes,peptides& hormones

DNA repair Nano robot.

Mechanism of robotic white blood cells

( Artificial white blood cells)

Swim through circulatory system

Ingesting ,destroying pathogens& converting them into non toxic substance
