High-Performance, Low-Cost SERS Substrates for Biosensing

A novel Surface-Enhanced Raman Scattering (SERS) substrate has been developed, offering a balance between cost-effectiveness and performance. This substrate features a gold layer with controlled topography, fabricated on a polymer base. This design aims to enhance Raman signal amplification for biosensing applications.

The approach focuses on achieving a defined gold nanostructure through a manufacturing process that seeks to reduce production costs. The polymer base provides mechanical stability and flexibility.

Initial studies have demonstrated the substrate's potential in biosensing applications, showing its ability to detect target molecules. This technology presents a solution for applications requiring SERS-based detection, including diagnostics, environmental monitoring, and food safety.
