Because light cannot penetrate deep into tissue, doctors are limited in their use of light-based treatments to, for instance, activate drugs. An international team of researchers led by Seok Hyun Yun of Harvard Medical School and Massachusetts General Hospital has developed a polymeric waveguide that delivers light deep into tissue and can then biodegrade (Nat. Commun. 2016, DOI: 10.1038/ncomms10374). In this demonstration, the researchers . . .
