Two-in-one nanotechnology punch knocks out drug resistant cancer cells

Cancer cells, like bacteria, can develop resistance to drug therapy, leading to relapse of disease. One approach showing promise in overcoming multidrug resistance in tumors is to combine two different anticancer agents in one nanoscale construct, providing a one-two punch that can prove lethal to such resistant cells.

Nanoparticles detect and purge metastases in lymph nodes

Researchers at the Winthrop Rockefeller Cancer Institute and the University of Arkansas for Medical Sciences have developed another fiber optic technique that can detect lymph node metastases and destroy them on the spot, an action that could prevent the further spread of breast cancer, melanoma, or gastrointestinal cancer, all of which spread through the lymphatic system.

Gold nanoparticles delivery platinum warheads to tumors

Cisplatin is one of the most powerful and effective drugs for treating a wide variety of cancers, but serious side effects ultimately limit the drug's use and effectiveness. Now, however, researchers have developed a nanoparticulate formulation of cisplatin that may be able to eliminate or reduce platinum-associated toxicity while boosting cisplatin's tumor-killing activity.

Carbon nanotubes fast forward seed germination

A collaborative team of biologists and nanotechnologists have demonstrated how seeds exposed to carbon nanotubes in the agar medium sprouted up to two times faster than control seed, a growth enhancement that has enormous potential on agriculture as well as plant-based biofuel production.

Next-generation carbon nanotube microcapsules deliver 'chemicals on demand'

Scientists in California are reporting development of a new generation of the microcapsules used in carbon-free copy paper, in which capsules burst and release ink with pressure from a pen. The new microcapsules burst when exposed to light, releasing their contents in ways that could have wide-ranging commercial uses from home and personal care to medicine.
