Context: Scientists from the Centre for Nano and Soft Matter Sciences (CeNS) have developed a new low-cost substrate that can increase the sensitivity of Surface-enhanced Raman spectroscopy (SERS), to help detect pollutants particles such as N-nitroso diphenylamine (NDPhA), a potent carcinogen and a severe threat to mankind
What is Raman spectroscopy?
Raman spectroscopy is a scientific technique that helps to identify and study the properties of different materials. It works by shining a laser beam on a sample and measuring the scattered light that comes back. This scattered light contains information about the chemical composition and structure of the material being studied, which can be used to identify different molecules and compounds.
Sir C.V. Raman was awarded the Nobel Prize in Physics in 1930 for his work on Raman spectroscopy.
