Synergistically Enhanced Ta₂O₅/AgNPs SERS Substrate Coupled with Deep Learning for Ultra-Sensitive Microplastic Detection.

ABSTRACT: Herein, a high-performance Ta₂O₅/AgNPs composite Surface-Enhanced Raman Scattering (SERS) substrate is engineered for highly sensitive detection of microplastics. Through morphology modulation and band-gap engineering, the semiconductor Ta₂O₅ is structured into spheres and composited with silver nanoparticles (AgNPs), facilitating efficient charge transfer and localized surface plasmon resonance (LSPR). This architecture integrates electromagnetic (EM) and chemical (CM) enhancement mechanisms, achieving an ultra-low detection limit of 10^-13 M for rhodamine 6G (R6G) with excellent linearity. Furthermore, the three-dimensional "pseudo-Neuston" network structure exhibits superior capture capability for microplastics (PS, PET, PMMA). To ad
