SERS Substrates Made With Pocket Change
Metal substrates needed for surface-enhanced Raman spectroscopy (SERS) can be made with everyday objects—even coins—reported Jordan F. Betz, a graduate student in Gary W. Rubloff’s research group at the University of Maryland. This simple approach allows substrates to be prepared quickly and easily for portable SERS analyses. Betz described how he and his coworkers developed the ability to turn loose change into SERS substrates in 30 minutes or less by using galvanic displacement . . .
