Nanoscopic changes to pancreatic cells reveal cancer: New spectroscopy technique may help detect deadly disease early
Though the new technique has not yet proven effective in double-blind clinical trials, it may one day help diagnose cancers of the pancreas and, potentially, other organs at their earliest and most treatable stages, before they spread.

Targeted Nanospheres Find, Penetrate, Then Fuel Burning Of Melanoma
Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reported in the Feb. 1 issue of Clinical Cancer Research.

Nanotubes Sniff Out Cancer Agents in Living Cells
A multidisciplinary team at the Massachusetts Institute of Technology (MIT) has developed carbon nanotubes that can be used as sensors for cancer drugs and other DNA-damaging agents inside living cells. The sensors, made of carbon nanotubes wrapped in DNA, can detect chemotherapy drugs such as cisplatin as well as environmental toxins and free radicals that damage DNA.
