Laser manipulation of plasmonic nanoparticles for SERS and sensing

Kapitel i bok, 2012

Optical tweezers have found widespread use in studies of biological macromolecules and in manipulation of microscopic objects, including biological cells and a variety of dielectric particles. But rapid progress over the last decade has demonstrated that optical tweezers also can be used as a powerful method for manipulation and control of plasmonic metal nanostructures. Here, we review our recent results in this area with a focus on the interaction between nanoparticles confined in an optical trap and applications in surface-enhanced Raman scattering spectroscopy.
