Preparation and Application of Two-Dimensional Ta4C3 MXene/Gold Nanostar Composite SERS Substrates for Thiram Detection

Surface-enhanced Raman scattering (SERS) is a novel spectroscopic technique that enables the identification of analytes through analysis of their unique chemical signatures. Its high sensitivity, specificity, and rapid response make it a valuable tool in a range of fields, including biological detection, food safety, and environmental monitoring. However, traditional SERS nanoparticle substrates are susceptible to instability and agglomeration. In this study, Ta
