9. Nanotechnology in Electronics
Nanotechnology holds some answers for how we might increase the capabilities of
electronics devices while we reduce their weight and power consumption.
16. Nanotechnology in Medicine
Drug Delivery
Nanotechnology in medicine currently being developed involves employing
nanoparticles to deliver drugs, heat, light or other substances to specific types of
cells (such as cancer cells)
18. Nanotechnology in Medicine
Therapy Techniques
Researchers have demonstrated a method to generate sound waves that are
powerful, but also tightly focused, that may eventually be used for noninvasive
surgery. They use a lens coated with carbon nanotubes to convert light from a
laser to focused sound waves.
19. Nanotechnology in Medicine
Diagnostic Techniques
Researchers are developing a nanoparticle intended to make very early detection
of cancer tumors easier. When the nanoparticles attach to a cancer tumors the
nanoparticles release "biomarkers", molecules called peptides. The idea is that
since each nanoparticle carries several peptides a high concentration of these
biomarkers will occur even at very early stages of cancer, allowing early
detection of the disease.
33. Nanotechnology in Food
• Nanotechnology is having an impact on several aspects of food science, from how food is
grown to how it is packaged. Companies are developing nanomaterials that will make a
difference not only in the taste of food, but also in food safety, and the health benefits that
food delivers.
• Zinc oxide nanoparticles can be incorporated into plastic packaging to block UV rays and
provide anti bacterial protection, while improving the strength and stability of the plastic film.
