Improving surface-enhanced Raman scattering effect using gold-coated hierarchical polystyrene bead substrates modified with postgrowth microwave treatment. Journal of Biomedical Optics 13 (6) : -. ScholarBank@NUS Repository. https://doi.org/10.1117/1.3050447||Abstract:||We report a novel postgrowth microwave heating implementation by selectively modifying hierarchical polystyrene (PS) bead substrates coated with gold (Au) films to effectively improve the surface-enhanced Raman scattering (SERS) effect on the analytes. The SERS signal of probe molecule rhodamine 6G (Rh 6G) on the microwave-treated Au-PS substrates can be improved by 10-fold, while the detection limit of Rh 6G in concentration can be enhanced by two orders of magnitude compared to the as-growth substrates. The high-quality SERS spectrum of saliva can also be acquired using the modified substrates, demonstrating the potential for the realization of the high-performance SERS substrates for biomedical applications. © 2008 Society of Photo-Optical Instrumentation Engineers.||Source Title:||Journal of Biomedical Optics||URI:||http://scholarbank.nus.edu.sg/handle/10635/67101||ISSN:||10833668||DOI:||10.1117/1.3050447|
