A nanolaser known as the spaser can serve as a super-bright, water-soluble, biocompatible probe capable of finding metastasised cancer cells in the blood stream and then killing these cells, according to a new research study. The study found the spaser can be used as an optical probe and when released into the body (possibly through an injection or drinking a solution), it can find and go after circulating tumor cells (CTCs), stick to them a...

Nanoparticles designed to block a cell-surface molecule that plays a key role in inflammation could be a safe treatment for inflammatory bowel disease (IBD), according to researchers in the Institute for Biomedical Sciences at Georgia State University and Southwest University in China. The scientists developed nanoparticles, or microscopic particles, to reduce the expression of CD98, a glycoprotein that promotes inflammation. Their findings ...
