TRANSCRIPT

  • Slide 1
  • Slide 2
  • Nano technology Definition of nano technology Nano shell Nano particles Carbon nano tubes &its application. Application of nano technology
  • Slide 3
  • Whats 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
  • Slide 4
  • The perfix nano means one bilionth 1nm=10 -9 meter. 80.000 nano particles in a raw are the width of a human hair
  • Slide 5
  • Slide 6
  • Formation of Nano shells
  • Slide 7
  • Slide 8
  • Preparation :coper,silver salts,oxides put together &heated to 600 0 c Deep Dish, Spain ZnO coated glass, TiO2 in paints.
  • Slide 9
  • scanning electron micrograph shows a carbon nanotube sheet pic2**/.An artificial muscle made from a sheet of these carbon
  • Slide 10
  • Application of nano technology 1- In medicine a-binding 5-fu drug to the CU (drug delivery) Pill camera has video chip& lab system ship
  • Slide 11
  • 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
  • Slide 12
  • Nano tubes based sensor that detect bacteria in drinking water, then happen treatment
  • Slide 13
  • 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.
  • Slide 14
  • Mechanism of robotic white blood cells ( Artificial white blood cells) Swim through circulatory system Ingesting,destroying pathogens& converting them into non toxic substance
  • Slide 15
