One of the major challenges in the quest to beat cancer is developing treatments that can selectively destroy cancer cells while leaving healthy cells unharmed. With this in mind, researchers at the Indian Institute of Technology Gandhinagar (IITGN) have devised a gold nanorod-based platform that delivers therapeutic agents specifically to the endoplasmic reticulum (ER), a structure responsible for protein production and processing within cells, while also generating heat when exposed to near-infrared light.
