Washington : A new research has revealed about an FDA-approved photodynamic therapy that on being combined with a new type of nanoparticle effectively kill deep-set cancer cells in vivo with minimal damage to surrounding tissue and fewer side effects than chemotherapy, reports ANI.

Lead author Gang Han from the University of Massachusetts Medical School said that they are very excited at the potential for clinical practice using their enhanced red-emission nanoparticles combined with FDA-approved photodynamic drug therapy to kill malignant cells in deeper tumors.

In photodynamic therapy, also known as PDT, the patient is given a non-toxic light-sensitive drug, which is absorbed by all the body’s cells, including the cancerous ones.

Red laser lights specifically tuned to the drug molecules are then selectively turned on the tumor area that kills the malignant cancer cells while leaving most neighboring cells unharmed.
