The function of extra-nasal olfactory receptors has the potential to be used in the diagnosis and treatment of health conditions such as cancer. The article is … Continue reading Smell receptors in the body could help sniff out disease

New ‘blood biopsies’ with experimental device may improve cancer diagnosis and follow-up

The investigators are conducting "liquid biopsies" by running blood through a postage-stamp-sized chip with nanowires 1,000 times thinner than a human hair and coated with antibodies, or proteins, that recognize circulating tumor cells. The device, the NanoVelcro Chip, works by "grabbing" circulating tumor cells, which break away from tumors and travel through the bloodstream, looking … Continue reading New ‘blood biopsies’ with experimental device may improve cancer diagnosis and follow-up
