Sensitive SERS detection of antibiotics using Ag-coated nanostructures fabricated by femtosecond laser cross-scanning.
The excessive use of antibiotics in medicine, agriculture, and aquaculture has led to widespread environmental contamination and public health concerns, underscoring the urgent need for rapid, sensitive, and cost-effective detection methods. Here, we report a scalable surface-enhanced Raman scattering (SERS) platform b...
