New nano drug candidate kills aggressive breast cancer cells

Researchers at the University of Arkansas have developed a new nano drug candidate that kills triple negative breast cancer cells. Triple negative breast cancer is one of the most aggressive and fatal types of breast cancer. The researchers linked a class of nanomaterials, called metal-organic frameworks, with the ligands of an already-developed photodynamic therapy drug to create a nano-porous material that targets and kills tumor cells without creating toxicity for normal cells.
