In a major breakthrough scientists have designed nanoparticles that can deliver drugs directly to a tumour. But what makes it special is that those nanoparticles that do not hit their target can be broken down and eliminated easily. The nanoparticle is encased in a shell coated with a peptide that enables it to target tumour cells. 'The disassembly is an interesting concept for creating drugs that respond to a certain stimulus' said Gary Braun a post-doctoral associate in the Ruoslahti Lab at University of California Santa Barbara.
