The device, which consists of gold nanoparticles embedded in a hydrogel that can be injected or implanted at a tumor site, could also be used more broadly to disrupt any gene involved in cancer.
“You can target any genetic marker and deliver a drug, including those that don’t necessarily involve drug-resistance pathways. It’s a universal platform for dual therapy,” says Natalie Artzi, a research scientist at MIT’s Institute for Medical Engineering and Science (IMES), an assistant professor at Harvard Medical School, and senior author of a paper describing the device in the Proceedings of the National Academy of Sciences the week of March 2.
