SERS Sensor Integrated in Stretchable and Antimicrobial Wrapper for Food Quality Monitoring and Preservation.

In the wellness era, where food quality and safety are paramount, traditional food-monitoring methods, such as ribotyping and polymerase chain reaction, are often destructive and time-consuming, limiting their practicality for widespread application. Surface-enhanced Raman scattering (SERS) sensing is a promising alternative that offers real-time, nondestructive, and highly sensitive capabilities. This study proposes a nanostructured SERS sensor integrated into a stretchable and antimicrobial wrapper (NSSAW).
