Nanofibers Carry Toxic Peptides Into Cancer Cells

(PhysOrg.com) -- Researchers have long known that certain peptides are capable of killing cells by inserting themselves into the cell membranes and disrupting normal membrane structure and function. Now, researchers at Northwestern University have learned how to deliver these cytotoxic peptides to tumor cells using self-assembling nanofibers that can slip into cancer cells and allow the toxic peptides to do their job from inside the cell.
