Image: Investigators loaded light-activated nanoshells (gold and light blue) with the anticancer drug lapatinib (yellow) by encasing the drug in an envelope of albumin (blue). Light from a near-infrared laser (center) was used to remotely trigger the release of the drug (right) after the nanoshells were taken up by cancer cells (Photo courtesy of A. Goodman, Rice University).

Gold Nanoshells Safely Deliver Toxic Chemotherapeutic Drugs

A novel method for delivering toxic drugs to tumor cells relies on the use of light-activated gold nanoparticles, which are triggered remotely by laser light to release the drugs inside the cancer cells. More...

Image: Circulating tumor DNA (ct or cfDNA) is found in serum and plasma fractions from blood. The mechanism of cfDNA release is unknown, though apoptosis, necrosis, and active secretion from tumor cells have been hypothesized (Photo courtesy of Wikimedia Commons).

Computer Program Confirms Relationship of cfDNA and Tumor DNA

Cancer researchers have developed an accurate, scalable approach for monitoring cell-free tumor DNA from blood samples. More...
