Through a nanolens brightly

Seeing individual molecules with Raman spectroscopy requires very intense optical fields. An arrangement of metal nanoparticles can provide the necessary boost. Researchers in the USA and Israel have devised a 'nanolens' capable of enhancing the strength of an optical field by a factor of a thousand or so. They show that arrangements of a few metal nanoparticles can generate the lensing effect, creating a small local hotspot of field intensity1. This hotspot could be used for single-molecule spectroscopy and for manipulation of nanoscale and molecular objects using optical tweezers.
