(Phys.org)—Advancements in surface-enhanced Raman spectroscopy using a scanning tunneling microscope under ultrahigh vacuum and low temperature have allowed a group of researchers from The University of Science and Technology of China to distinguish two different, but structurally similar, adjacent molecules adsorbed on a silver surface. This level of precision and sensitivity could allow for advancements in surface chemistry and precise monitoring of DNA sequencing and protein folding. Their work appears in a recent issue of Nature Nanotechnology.
