- 7. NANOTECHNOLOGY OVERVIEWWhat isTechnology?Technology – the branch of knowledge that deals with creation in the fields of :- Engineering- Industrial arts- Applied science - Pure scienceNow what is Nanotechnology?- The engineering of functional systems at a molecular scale- The manipulation of the structure of matter at the molecular level- The “bottom up” approach of building materials from a nanometer scale using techniques and tools being developed today to make complete, highly advanced products. - Basically mean small technology

- 9. NANOBOTSNANOTECHNOLOGY IN ENGINEERING2.1 NANOMACHINES I-switch- ADNA nanomachine- Externally triggered by protons - Based on fluorescence resounance energy transfer(FRET)- Functions as a pH(a measure of acidity) sensor
- 10. NANOTECHNOLOGY IN ENGINEERINGDrosophilacells with the I-switch inside their endosomes.I-switch mapping out spatial and temporal pH changes associated with endosome maturation.
- 11. NANOTECHNOLOGY IN ENGINEERINGNanoimpellers -Nanotubes made of light-sensitive silica - Carries cancer-killing drugs- Targets only cancer cells- Injected into human cancer cells in vitro How does it work? When light strikes the silica- Tiny tails inside the tubes wag back and forth- Creates a current that releases the drugs out of the tube
