27 August 2014 New physics and applications of apertures in thin metal films
Author Affiliations +
The nanoplasmonic properties of apertures in metal films have been studied extensively; however, we have recently discovered surprising new features of this simple system with applications to super-focusing and super-scattering. Furthermore, apertures allow for optical tweezers that can hold onto particles of the order of 1 nm; I will briefly highlight our work using these apertures to study protein - small molecule interactions and protein - DNA binding.
