Transcript of Untitled Prezi

-Stain-repellent.
-cloth treatment.
- type A is caused by blocked blood vessels in the retina ( the tissue were the images are formed) the robot delivers an extremely small dose of medicine to restore blood flow & vision.
- can take 55,000 pictures over the course of 8 hours.
- has wireless transmitter which transmit the images to the data recorder wearing over the waist.
- Made of : inert plastic that doesn't create a toxic response.
oxidative stress, inflammation, and consequent damage to proteins, membranes and DNA.
What's Nanotechnology?
-Nano is Greek for "dwarf".
-Smaller than human hair (80,000nm).
-Manipulation of matter < 100nm.
-1nm = 1/1,000,000,000m
-It can change properties of any material.

Nario Taniguchi
"Japanese scientist
was the first to use the term "
Nano_technology
" in a conference
1991
Sumio Lijima
(Japanese scientist):
discovered carbon nanotubes.(
fullerene particles
).
Beating Cancer Cells to Death with Gold Nanoparticles in More than One Way

Danger of Nanotechnology...

It’s green, it’s clean, and it’s never seen That’s nanotechnology
!


-Nanotech. is a double edged sward .
-Typical nanoparticles are..
titanium dioxide, alumina, zinc oxide, carbon black, and carbon nanotubes
.
-the can translocate from their site of deposition to distant sites such as the blood and to the blood brain .
-Nanoscale silver, which has been added to toys, toothpaste, clothing for its antimicrobial properties, produces
substantial DNA damage
.
Primary mechanisms of nanoparticle toxicity
The greater chemical reactivity of nanomaterials increases
reactive oxygen species
(
ROS
), including
free radicals.
& cause :
On the other side,
Demokritou's lab
(Harvard School of Public Health (HSPH)) recently showed that
coating zinc oxide particles
with a nano thin layer of
amorphous silica
can
reduce
the particles' ability to
damage DNA
.
