-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.

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
.
