Kiss-and-tell: A new method for precision delivery of nanoparticles and small molecules to individual cells

The delivery of experimental materials to individual cells with exactness and exclusivity has long been an elusive and much sought-after ability in biology. With it comes the promise of deciphering many longstanding secrets of the cell. A research team has now successfully shown how small molecules and single nanoparticles can be applied directly onto the surface of cells. In the study the scientists describe their technique as a ' kiss' (microkiss) -- an easy and cost-effective new method, unlocking new possibilities in single-cell science with a view towards next generation therapeutic applications.
