Silver nanoparticles take spectroscopy to new dimension
A new way of organizing nanostructures has boosted Raman signals by a hundred thousand times to better identify and characterize different molecules

Summary:
As medicine and pharmacology investigate nanoscale processes, it has become increasingly important to identify and characterize different molecules. Raman spectroscopy, which leverages the scattering of laser light to identify molecules, has a limited capacity to detect molecules in diluted samples because of low signal yield, but researchers in India have improved molecular detection at low concentration levels by arranging silver nanoparticles on silicon nanowires.
