Nano technology • 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
Preparation :coper,silver salts ,oxides put together &heated to 6000c ZnO coated glass, TiO2 in paints. Deep Dish, Spain
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? • Block u.v light • 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
