5x stronger than steal 50x tensile strength, or breaking strain than steelcan be metallic or semiconducting depending on their structure
pressure up to 24 GPa without deformationsuperhard phase nanotubes is 462 to 546 GPa, even higher than that of diamond (420 GPa for single diamond crystal)The temperature stability of carbon nanotubes is estimated to be up to 2800 °C in vacuum and about 750 °C in air
Nanotechnology in Medicine Drug DeliveryNanotechnology in medicine currently being developed involves employingnanoparticles to deliver drugs, heat, light or other substances to specific types ofcells (such as cancer cells)
Nanotechnology in Medicine Therapy Techniques Researchers have demonstrated a method to generate sound waves that arepowerful, but also tightly focused, that may eventually be used for noninvasivesurgery. They use a lens coated with carbon nanotubes to convert light from alaser to focused sound waves.
Nanotechnology in Medicine Diagnostic TechniquesResearchers are developing a nanoparticle intended to make very early detectionof cancer tumors easier. When the nanoparticles attach to a cancer tumors thenanoparticles release "biomarkers", molecules called peptides. The idea is thatsince each nanoparticle carries several peptides a high concentration of thesebiomarkers will occur even at very early stages of cancer, allowing earlydetection of the disease.
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.
