III BIOCHEMISTRY

2. Nanotechnology?
 Manipulating materials
and systems at the
scale of atoms and
molecules.
 Application of
technology using
materials from 1nm to
100nm.
 Interdisciplinary course

3. Medicine
 Stem cell differentiation
 Artificial DNA
 Chemotherapy.
 Destroy cancer cells without damaging the host cells.
 Silicon, gelatin nanoparticles, gold and silver.
 Vaccine, oral – enzyme preventing reproduction of viruses
(current).
 Graphene – computer contact lens due to transparency,
cancer marker, and wound healing

4. Electronics
 Flexible mobiles.
 Sensitive touch – detect even 1 atom.
 Battery charge in 5 seconds!! (electrical
conductivity).
 Storage, transformation, weight reduction,
manufacturing developments.
 Eco friendly recyclable.
 Cadmium selenide nanocrystals, Ag, Cu, C
nanotubes, etc.,

5. Environment
 Desalination of water.
 Fe – organic solvent cleaning in water.
 Silver nanoclusters – reduce pollution caused by
propylene oxide.
 Epoxy containing carbon nanotubes – increase
electricity generated by windmills.
 Increase storage of solar cells.

6. Fashion
 Cosmetics: Titanium dioxide – UV protective.
 Silver nanoparticles - kill bacteria (odour-resistant cloth).
 Skin care - vitamins deeper into the skin.
 Armour dress – nanofabrics.
 Clothes that react automatically to the environment.
 Garments water- and stain-repellent or wrinkle-free.
 Carbon nanoparticle.

7. Agriculture
 Growth of plant hormone.
 Increase yield and fertilization.
 Agriculture waste products in
production of graphene.
 Carbon nanotube – identify and
kills pathogens.
 Nano manipulation of seeds.

8. Food
 Zinc oxide – antibacterial.
 Nanosensors and dispensers.
 Tio2 in food packaging.
 Cover the surface – prevent entering of microbes –
preservative.
 Cocoa NanoClusters - (canola cooking oil )Canola Active Oil,
Nanotea and Nanoceuticals Slim Shake Chocolate.
 Pesticides encapsulated nanoparticles- pesticide within insect's
stomach.

9. Construction
 Structural stability.
 Carbon nanoparticles – crack prevention.
 TiO2 – rapid hydration and self cleaning.
 Aeroplane – less weight and mechanical stability.
 Paints – corrosion resistant and prevents fading.

10. Daily life
 Lab on chip.
 nano newspapers.
 Easy to clean pots – nanoclays.
 Nano-whiskers pants – water and stain resistant.
 Carbon nanotube – tennis balls –increase force and
accuracy.
 Silver nanoparticles – detergents, perfumes and
water purifiers.

11. Conclusion
 Rapidly growing promising field.
 Both advantages and disadvantages.
 Nanotech would be an undeniable force in the
future.
 Biodegradable.
 Takes time.
