Detecting RNA virus in saliva samples using Raman Spectroscopy

Researchers at the Mumbai-based Tata Memorial Centre have used Raman Spectroscopy to detect RNA viruses present in saliva samples. It is a proof-of-concept study to analyse non-infectious RNA viruses using conventional Raman Spectroscopy without using any additional reagent to enhance the signal. If Israel developed a spectroscopy-based one-minute breathe analyser to detect coronavirus, a team … Continue reading Detecting RNA virus in saliva samples using Raman Spectroscopy

Easy way to tell if the foil used in Thanjavur painting is gold or fake

By turning to Raman spectroscopy, a non-destructive tool, a researcher at Indian Institute of Technology (BHU) Varanasi has found an easy way to check if the gold foil used in Thanjavur paintings is genuine or not. Currently, there is no regulatory mechanism in place to check the quality of gold used in Thanjavur paintings despite the … Continue reading Easy way to tell if the foil used in Thanjavur painting is gold or fake
