Researchers from Cedars-Sinai and UCLA have been conducting biopsies on a postage stamp size chip called the NanoVelcro Chip.
This chip can help healthcare professionals monitor cancer patients.
Its design includes nanowires that are 1,000 times thinner than a strand of human hair, according to Science Daily. It works by “grabbing” the tumor cells that have detached from tumors and are flowing through the bloodstream.
