Nano Technology

1. IT’s

2. Application
And
Impact

3. Key Points :
1. Richard Feynman -1965.
2. Approaching Nanotechnology.
3. Size explanation.
4. Nanofood - Nano Technique used during cultivation ,production,processing or
packaging of food.
5. Nanocomposite ( A nanocomposite is a multiphase material in which, in
contrast to microcomposites, one of the phases has one, two, or three
dimensions of less than 100nm, or the composite phases have nanoscale
distances between them.)
6. Nanocapsule (Nanocapsules are nanoscale shells consisting of a nontoxic
polymeric membrane that encapsulates a liquid core; desired products are placed
inside this shell.)

4. Nanocomposite

6. Used In :
1. To deliver nutrients.
2. Nano vitamin drinks.
3. Nanocomposite coating in food.
4. Safety Packaging( Nano wrapper).
5. Nanoclay coating in beer bottles ,ketchup bottles.
6. Carrier of essential oil.
7. Encapsulating nanoparticle around active ingredient .
8. Protein coated nanocantilever.
9. Less preservatives can be used.
10. Improved packaging.(improve barrier property)
11. Active packaging.(provide antimicrobial property)
12. Smart packaging.(detect spoilage)

9. Impacts :
1. Hazardous to Environment and human health.
2. Surface area increases - high reactive - direct impact.
3. Ultrafines combustion particulate cause pulmonary pathologies.
4. Easily gets entrapped by cell by cell drinking ,cell eating.
5. Carbon nanotubule inhalation causes cancer.
6. Also leads to increased bioaccumulation.
7. Nanopollution.
8. It has large tendency to form aggregate so greatly affect marine life.
9. Quantum dot toxicity.

13. The Irony Is that The
Actual Story Starts
When You Think It Got Ended Up.
