A Superhydrophilic Au-Coated Monolayer Polystyrene Sphere Substrate for Uniform Surface-Enhanced Raman Spectroscopy
-fold and a limit of detection down to the micromolar range using Rhodamine 6G as a probe molecule. The scalable fabrication and consistent performance highlight the potential of this substrate for cost-effective and practical sensing applications. Furthermore, detecting trace levels of the toxic paraquat herbicide is demonstrated, indicating the potential for real-world applications.
