Solar cells could be pitted against cancer cells to create a faster, less painful and more effective form of treatment.
A microscopic version of solar cells could be used to treat cancer.
Like larger solar cells, the tiny tech would absorb light and convert it into electricity.
The charged miniature solar cell would then deliver a drug to attack a tumor while healthy cells would remain unaffected.
Photovoltaics are often touted as potential game-changers as a source of alternative energy, but new microscopic versions of solar cells could soon be lifesavers for millions of cancer patients.
Scientists are developing new solar cell-powered cancer therapies that could -- if approved for clinical use -- make treatment faster, less painful and more effective.
"I looked at one report from Sandia National Labs about how they could fabricate their really small solar cells," said Tao Xu, a scientist at the University of Texas at El Paso, who recently presented his research at the AVS conference, "and I figured we could probably use this new device for biomedical research -- in particular to develop a target that could deliver cancer therapies."
