Description
Summary:Vibrational spectroscopy has proven itself to be a valuable contributor in the study of various fields of science, primarily due to the extraordinary versatility of sampling methods. Raman measurement gives the vibrational spectrum of the analyte, which can be treated as its “fingerprint,” allows easy interpretation and identification. Over the last years, there has been tremendous technical improvement in Raman spectroscopy, as overcome by the problems like fluorescence, poor sensitivity or reproducibility. This article reviews the recent advances in Raman spectroscopy and its new trend of applications ranging from ancient archaeology to advanced nanotechnology. It includes the aspects of Raman spectroscopic measurements to the analysis of various substances categorized into distinct application areas such as biotechnology, mineralogy, environmental monitoring, food and beverages, forensic science, medical and clinical chemistry, diagnostics, pharmaceutical, material science, surface analysis, etc. Advances in the instrumental design of Raman spectrometers coupled with newly developed sampling methodologies have also been described which enable trace level detection and satisfactory analysis.
