Remote-control shoots laser at nano-gold to turn on cancer-killing immune cells

Cancer immune cell therapy has made headlines with astounding successes like saving former US President Jimmy Carter from brain cancer. But immunotherapy has also had many tragic flops. Researchers working to optimize the innovative treatment have implanted a genetic switch that activates T-cells when they are inside of tumors. Remote-control light waves resembling those used in a TV remote combine with gold nanorods to flip the switch. (Mehr in: Cancer News — ScienceDaily)
