Surface-Enhanced Raman Spectroscopy and Plasmonic Nanomaterials for Sensitive Detection
This community develops nanostructured materials and optical methods to detect and analyze molecules with high sensitivity, primarily using surface-enhanced Raman spectroscopy (SERS) and plasmonic nanoparticles.
The work centers on the synthesis and characterization of gold and silver nanoparticles, including nanorods and core-shell structures, to create substrates that amplify Raman signals. Recurring themes include the design of plasmonic nanoarrays, the application of machine learning to interpret spectral data, and the use of near-infrared and circularly polarized light for chiral sensing. The research spans fundamental studies of localized surface plasmon resonance to applied techniques for rapid, sensitive detection of biological and chemical targets.
The largest share of the community's output is found in gold research, accounting for 4.9% of all gold research, and 9,150 papers here; silver research follows with a 4.6% share and 7,704 papers.
The community comprises 32,443 papers, publishing most frequently in Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, Journal of Raman Spectroscopy, and The Journal of Physical Chemistry C.
Recent work focuses on integrating SERS with artificial intelligence and microfluidics for biomedical applications, developing dual-tunable substrates using hybrid materials, and improving the selectivity and stability of detection boundaries in semiconductor-based SERS systems.
