Polymer Nanoparticle Kills Tumors

Photodynamic therapy (PDT), which uses a light-sensitive chemical known as a photosensitizer to produce cell-killing “reactive oxygen,” has become an important option for the treatment of esophageal cancer and non-small cell lung cancer. Current photosensitizers, however, produce significant side effects, including sensitivity to the sun, that limits their wider use in treating cancer.
