Coadministration of paclitaxel and curcumin in nanoemulsion formulations to overcome multidrug resistance in tumor cells

Cancer cells, like bacteria, can develop resistance to drug therapy. In fact, research suggests strongly that multidrug-resistant cancer cells that remain alive after chemotherapy are responsible for the reappearance of tumors and the poor prognosis for patients whose cancer recurs.

Nanoscopic 'pearl necklaces' track and attack cancer cells

A team of investigators at Purdue University has developed nanoscale probes that can help pinpoint the location of tumors and might one day be able to directly attack cancer cells.

Nanosensor arrays ''sniff out" cancer

In 2006 researchers established that dogs could detect cancer by sniffing the exhaled breath of cancer patients. Now, using nanoscale arrays of detectors, two groups of investigators have shown that a compact mechanical device also can sniff out lung cancer in humans.
