Single 5-nm quantum dot detection via microtoroid optical resonator photothermal microscopy
Abstract Label-free detection techniques for single particles and molecules play an important role in basic science, disease diagnostics, and nanomaterial investigations. While fluorescence-based methods are tools for single molecule detection and imaging, they are limited by available molecular pro...
