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.
