Trace-Level Detection of Explosives Using Sputtered SERS Substrates
June 1st 2017This study explores the use of a novel SERS substrate that can enhance the Raman signals of explosives that are present in picogram quantities in neat solutions using a visible laser wavelength and a compact Raman instrument.
1064-nm Raman: The Right Choice for Biological Samples?
June 1st 2017Interference from background fluorescence is a common challenge in Raman analysis. A study of three different types of biological samples was made to compare the ability of 785-nm and 1064-nm excitation to deal with this problem.
