Cancer Nanomedicine is developing to cover a wide range of applications from imaging, diagnosing to treating cancers with targeted therapies. Cancer Nanomedicine works on the theory that nanometer sized particles of gold, nanomicelles and quantum dots (QDs) have unique functional properties that differ from other available discrete [...]
Researchers at the University of Arkansas have developed a novel imaging technique that uses coated carbon nanotubes to map lymphatic endothelial cells for detecting cancer metastasis in sentinel lymph nodes. … With this technique it was demonstrated that the golden nanoparticles could be used to diagnose and treat the cancer at a cellular level.
A group at the University of Tokyo have found a type of anerobic marine bacteria that produce magnetosomes, which are thought to help them navigate by following the earths magnetic field.
These magnetosomes are formed by filling fatty vesicles with iron. This iron is then oxidised to form magnetite a highly magnetic form of iron. These magnetite crystals [...]
At the University of North Carolina there has been a nanotechnology breakthrough in X-ray imaging. The breakthrough has come from carbon nanotubes being used to create a novel multi-beam source of X-rays. The carbon naotubes can be used as tiny electron guns, which dont have to heat up to create the X-rays. This means the [...]
