Abstract

Optical detection of nanoscale objects without relying on fluorescence is a current challenge due to their extremely weak interaction with light. Resonator-enhanced absorption microscopy is a novel tool to heavily boost the light-matter interaction. It combines highly sensitive, spatially resolved imaging with spectroscopy, offering a competitive alternative to established methods for the detection and analysis of nanoscale systems in nanotechnology, material design, and the life sciences.
