Tests at Rice University’s Brown School of Engineering of a two-dimensional Janus compound showed it could be an effective and universal platform for improving the detection of biomolecules via surface-enhanced Raman spectroscopy (SERS).
Monolayer Janus MoSSe, a compound of molybdenum, sulfur, and selenium developed at Rice University, is adept at detecting biomolecules via surface-enhanced Raman spectroscopy. Its nonmetallic nature helps by curtailing background noise in the signal. Courtesy of Lou Group/Rice University.
Using glucose to test the material proved its ability to boost its Raman enhancement factor by more than 100,000 times, which the researchers say is comparable to the highest-reported enhancement…
