资源简介：
Chalcogenopyrylium nanotags demonstrate an unprecedented performance with a retina safe, 1550 nm laser excitation. These unique nanotags consisting of chalcogenopyrylium dyes and 100 nm gold nanoparticles produce exceptional SERS signals with picomolar detection limits obtained at this extremely red-shifted and eye-safe laser excitation. Figure 1 – SERS comparison study between the commercial nanotag and the chalcogenopyrylium nanotags 1 and 2. Figure 2 - SERS particle dilution studies for chalcogenopyrylium nanotags 1 and 2 and the commercial nanotag over the concentration range 1.7 nM to 80 pM. The dataset is embargoed for six months while a patent application is developed. See Readme file for details on file content.
