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
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
