A comparative study of plasmonic-enhanced single-molecule fluorescence induced by gold nanoantennas and its application for illuminating telomerase†
Abstract
A comparative study of plasmonic-enhanced single-molecule fluorescence (PESMF) induced by four gold nanoantennas is reported. The gold triangular nanoplate (Au TNP) is the optimal PESMF substrate for Cy5.5 owing to its sharpest point and strongest electric fields. The Au TNP is chosen for the preparation of a telomerase sensor.
