Remote-Control Shoots Laser at Nano-Gold to Turn on Cancer-Killing Immune Cells | Research Horizons

Cancer immune cell therapy has made headlines with astounding successes like saving former U.S. President Jimmy Carter from brain cancer. But immunotherapy has also had many tragic flops. Georgia Tech 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. Bioengineering and Bioscience Electronics and Nanotechnology
