Metal Nanoparticles Offer New Imaging Method

Richard Gaughan

As biochemical investigations focus on ever-smaller structures, methods for detecting elements as small as single molecules must be developed. The ideal label would be small enough to have no impact on molecular activity, yet would have a constant interaction cross section large enough to make the molecule easily detectable. Researchers in France and the Netherlands have recently demonstrated the imaging of nanometer-size metal particles, an approach that promises high contrast, small size and a constant detection cross section for single-molecule studies. Metallic nanoparticles could...Read full article
