Sensing and Identification of Health Hazardous Molecular Components using Surface-Enhanced Raman Spectroscopy: A Mini Review

Abstract

The use of various adulterants and harmful chemicals is rapidly increasing in various sectors such as agriculture, food, and pharmaceuticals,and they are also present in our surroundings in the form of pollutants. The regular and repeated intake of harmful chemicalsoften adversely affects human health. The prolonged exposure of living beings to such adverse components can lead to severehealth complications. To avoid the unlimited utilization of these chemical components, a sensing technology that is sensitive and reliablefor low-concentration detection is beneficial. Surface-enhanced Raman spectroscopy (SERS) is a powerful method for identifying lowrangeconcentrations of analytes, leading to great applications in molecular identification, including various diagnostic biomarkers. SERS in chemical, gas, and biological sensors can be an excellent approach in the sensing world to achieve rapid and multiple-analytedetection, leading to a new and efficient approach in healthcare monitoring.
