Nano Polystyrene beads

Nanoaperture fabrication via colloidal lithography for single molecule fluorescence analysis. In single molecule fluorescence studies, background emission from labeled substrates often restricts their concentrations to non-physiological nanomolar values. Djou Ounas One approach to address this challenge is the use of zero-mode waveguides (ZMWs), nanoscale holes in a thin metal film that physically and optically confine …
