Researchers at Texas A&M University have invented a technology that can drastically downsize the apparatus used for Raman spectroscopy.
“Raman benchtop setups can be up to a meter long depending on the level of spectroscopic resolution needed,” said Pao-Tai Lin, assistant professor in the Department of Electrical and Computer Engineering and the Department of Materials Science and Engineering. “We have designed a system that can potentially replace these bulky benchtops with a tiny photonic chip that can snugly fit within the tip of a finger.”
