In a first, IISc team directly delivers protein into cells - The Hindu

In a breakthrough that might have huge medical implications, researchers at Bengaluru’s Indian Institute of Science (IISc) have used a novel strategy to directly deliver proteins into mammalian cells. Proteins are big molecules and so cannot enter the cells on their own. So a team from IISc substituted a hydrogen atom of the protein with an iodine atom to achieve a nearly sixfold increase in protein uptake by cells.
