Machine learning assisted biomimetic flexible SERS sensor from seashells for pesticide classification and concentration prediction

• A new type of stable biomimetic SERS sensor with a shell surface structure has been synthesized. • Combining machine learning to classify and predict pesticide types and concentrations. • The sensor is simple to fabricate, environmentally friendly, and has high performance. Complex surface structures are among the critical materials for fabricating sensors for surface-enhanced Raman scattering. In this study, a novel biomimetic sensor was fabricated by replicating the surface structure of seashells, and uniform silver nanoparticles were imparted to it via in-situ synthesis. The natural surface structure of seashells, characterized by numerous pores, folds, and protrusions, plays a pivotal role in creating…
