Accessing Properties of Molecular Compounds Involved in Cellular Metabolic Processes with Electron Paramagnetic Resonance, Raman Spectroscopy, and Differential Scanning Calorimetry

Abstract

In this work, we review some physical methods of macroscopic experiments, which have been recently argued to be promising for the acquisition of valuable characteristics of biomolecular structures and interactions. The methods we focused on are electron paramagnetic resonance spectroscopy, Raman spectroscopy, and differential scanning calorimetry. They were chosen since it can be shown that they are able to provide a mutually complementary picture of the composition of cellular envelopes (with special attention paid to mycobacteria), transitions between their molecular patterning, and the response to biologically active substances (reactive oxygen species and their antagonists—antioxidants—as considered in our case study).

Advance in Detection Technique of Lean Meat Powder Residues in Meat Using SERS: A Review

“…Surface-enhanced Raman scattering (SERS) is a technique that enhances the Raman scattering strength of a target molecule by adsorbing it on the surface of a metal nanoparticle [27][28][29]. SERS technology can increase the Raman signal intensity of target molecules by 10 6 -10 14 times, which is characterized by high sensitivity, fast detection speed, low detection cost, easy operation, and portability [30,31]. Currently, SERS technology has been successfully applied in the fields of environment, public safety, bioanalysis, pollutant monitoring, and food safety [32][33][34][35].…”
