Surface-Enhanced Raman Spectroscopy (SERS): Applications in Nanotechnology, Biomedicine, and Environmental Analysis

By
Surface-Enhanced Raman Spectroscopy (SERS): Advancing Sensitivity and Applications Surface-Enhanced Raman Spectroscopy (SERS) is an advanced analytical technique that significantly enhances the Raman scattering of molecules when supported by nanostructured materials. This high sensitivity makes it an invaluable tool for various fields, including environmental monitoring, biomedicine, and nanotechnology. Here’s an in-depth look at SERS and its applications: 1. What is Surface-Enhanced Raman Spectroscopy (SERS)? Highly Sensitive : SERS amplifies the Raman scattering signal, allowing for the detection of even trace amounts of molecules, which would otherwise be undetectable using standard Raman spectroscopy. Nanostructured Materials : The technique uses nanostructures (such as gold or silver nanoparticles) to enhance the Raman signal, which is why it’s called "surface-enhanced." 2. Principles of Raman Spectroscopy Non-Destructive Chemical Analysis : Raman spectroscopy is widel...
