To force cargo-loaded red blood cells to dump their contents, scientists decorated the cells with gold nanoparticles and zapped them with a laser (ACS Nano, DOI: 10.1021/nn3006619). Scientists aim to use such cells to deliver drugs to tumors, because red blood cells are naturally compatible with the immune system and circulate in the body for days. Other researchers have found ways . . .
