Researchers figure out why gold nanoparticles can penetrate cell walls
Date:8/22/2013

erting biosensing molecules on or into certain cells, Van Lehn says. In this way, scientists could detect or monitor specific biochemical markers, such as proteins that indicate the onset or decline of a disease or a metabolic process.

In general, attachment to nanoparticles' surface coatings could provide a key to cells' interiors for "molecules that normally wouldn't have any ability to get through the cell membrane," Irvine says.
