Selective melamine detection in multiple sample matrices with a portable Raman instrument using surface enhanced Raman spectroscopy-active gold nanoparticles
A surface enhanced Raman spectroscopic (SERS) mapping technique was applied to qualitatively detect and characterize gold nanoparticles on and in spinach leaves in situ.
We develop an ultrasensitive “turn off” Surface Enhanced Raman Spectroscopy (SERS) sensor for the detection of heparin based on the anti-aggregation of 4-mercaptobenzoic acid stabilized gold nanoparticles.
