Nanomedicine is the medical application of nanotechnology. [1] Nanomedicine ranges from the medical applications of nanomaterials and biological devices, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology such as biological machines.
As nanotechnology is an emerging field, there is great debate regarding to what extent nanotechnology will benefit or pose risks for human health. Nanotechnology's health impacts can be split into two aspects: the potential for nanotechnological innovations to have medical applications to cure disease, and the potential health hazards posed by ...
Nanotechnology has the potential to benefits all forms of work from daily life to medicine and biology. Despite these benefits, there are also health risks when it comes to human exposure to the nano material. Studies have shown that dangerous nano-particles can build up in the body after prolonged exposure.
Selected tissue distribution studies on one of these nanotubes, {([Na+][1-Me-2-((CH2)4NH-)-1,2-C2B9H10][OEt])n(SWCNT)} (Va), showed that the boron atoms are concentrated more in tumors cells than in blood and other organs, making it an attractive nanovehicle for the delivery of boron to tumor cells for an effective boron neutron capture therapy ...
Nanotechnology is giving rise to nanographene batteries that can store energy more efficiently and weigh less. [26] Lithium-ion batteries have been the primary battery technology in electronics for the last decade, but the current limits in the technology make it difficult to densify batteries due to the potential dangers of heat and explosion ...
Nano Biomedicine and Engineering is a quarterly peer-reviewed open-access scientific journal that was established in 2009 covering nanotechnology applied to biology, medicine, and engineering. It is published by the Tsinghua University Press and sponsored by Shanghai Jiao Tong University .
It can be directed to the location of cancer cells with sustained release behavior. Studies have also been done on gold nanoparticle responses to local near-infrared (NIR) light as a stimuli for drug release. In one study, gold nanoparticles functionalized with double-stranded DNA encapsulated with drug molecules, were irradiated with NIR light.
While there are many in vitro studies of gold nanoparticles used for chemotherapy, in vivo studies are both rare and often report conflicting results. For example, one in vivo study has shown that 13-nm gold nanoparticles circulated in the bloodstream often “accumulate in the liver and spleen and…have long blood circulation times."
