Tissue-penetrating light releases chemotherapy inside cancer cells

An innovative technique that can carry chemotherapy safely and release it inside cancer cells when triggered by two-photon laser in the infrared red wave length has been developed. A light-activated drug delivery system is particularly promising, because it can accomplish spatial and temporal control of drug release. Finding ways to deliver and release anticancer drugs in a controlled manner that only hits the tumor can greatly reduce the amount of side effects from treatment, and also greatly increase the cancer-killing efficacy of the drugs. The difficulty of treating cancer often derives from the difficulties of getting anticancer chemotherapy drugs to tumor cells without damaging healthy tissue in the process. Many cancer patients experience treatment side effects that are the result of drug exposure to healthy tissues.
