“‘Spased’ Out” — The Discovery Files

A nanolaser known as the spaser can serve as a super-bright, water-soluble, biocompatible probe capable of finding metastasized 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, stick to them and destroy these cells by breaking them apart to prevent cancer metastases.
