A look at the state of the art in cancer therapies under development from h+ Magazine: "Nanomedicine, an offshoot of nanotechnology, refers to highly specific medical intervention at the molecular scale for curing disease or repairing damaged tissues, such as bone, muscle, nerve, or brain cells. Nanoparticles - anywhere from 100 to 2500 nanometers in size - are at the same scale as the biological molecules and structures inside living cells. ... Titanium dioxide is not the only nanoparticle that shows promise in cancer therapy. Gold nanospheres - nearly perfectly spherical nanoparticles that range in size from 30 to 50 nanometers - are being used to search out and 'cook' cancer cells. The cancer-destroying nanospheres show promise as a minimally invasive future treatment for malignant melanoma, the most serious form of skin cancer. ... The hollow gold nanospheres are equipped with a special peptide that draws the nanospheres directly to melanoma cells, while avoiding healthy skin cells. After collecting inside the cancer, the nanospheres heat up when exposed to near-infrared light, which penetrates deeply through the surface of the skin."
