Nanoparticles deliver chemotherapy when hit with a targeted light

Researchers at UCLA's Jonsson Comprehensive Cancer Center have developed a light-activated delivery system for chemotherapy. The drugs are held within nanoparticles that are stoppered with tiny capping molecules, but when tissue-penetrating energy reaches the nanoparticles, the drug is released. The scientists noted that the system could be effective in treating cancers such as breast, stomach, colon or ovarian. More
