TY  - JOUR
AB  - We demonstrate stimulated emission depletion (STED) microscopy with 20 nmgold nanospheres coated by fluorescent silica. Compared with previousdemonstrations of STED with a hybrid plasmonic fluorescent label, the currentimplementation offers a substantially smaller label and a better resolutionimprovement of up to 2.5-fold beyond the diffraction limit of confocalmicroscopy. This is achieved at approximately 2 times lower intensity thanconventional STED based on dyes alone, and in an aqueous environment,demonstrating the relevance to bio-imaging. Finally, we also show, for thefirst time in this context, a 3-fold reduction in the rate of photobleachingcompared to standard dye-based STED, thus, enabling brighter images.
