Nanoparticle that can seek and destroy brain cancer cells
Scientists in Illionis are developing the fist ever nanoparticle that can seek and destroy brain cancer cells without causing any damage to nearby cells.
The Studies shows that Titanium dioxide nanoparticles, witch are light sensitive particles which are used in sunscreens can destroy cancer cells when it is exposed to ultraviolet light. Even if it is effective in destroying caner cells scientists had difficulties in getting nanoparticles, each about 1 by 50,000th the width of a human hair, to target and enter cancer cells while avoiding healthy cells.
The solution involves chemically linked titanium dioxide nanoparticles to an antibody that recognizes and attaches to GMB cells. The nanoparticles killed up to 80 percent of the brain cancer cells after 5 minutes of exposure to focused white light.The positive result of these experiments are a good hope for brain cancer treatment.
