This paper introduces a highly absorbent and sensitive cellulose nanofiber (CNF)/gold nanorod (GNR)@Ag surface-enhanced Raman scattering (SERS) sensor, fabricated using the vacuum filtration method. By optimizing Ag thickness in GNR@Ag core-shell structures integrating them with CNFs, optimal SERS hotspots were identified probe molecule 4-aminothiophenol (4-ATP). To concentrate pesticides extracted from fruit vegetable surfaces, we utilized evaporation enrichment effect hydrophilic CNF hole-punched hydrophobic polydimethylsiloxane (PDMS). design leverages substrate localized to create microfluidic flow that concentrates analytes within small hole area, enhancing sensitivity by up 465 %. The sensor achieved on-site detection limits for Thiram as low 10-11 M on specifically apples chili peppers. approach underscores how can substantially improve field-based pesticide analysis. sensor's response interfering substances (e.g., glucose citric acid) other harmful molecules carbendazim nitrofurazone was also evaluated, demonstrating high accuracy). PDMS-assisted CNF/GNR@Ag exhibits flexibility, ease of fabrication, excellent selectivity, showing significant potential applications food safety, agriculture, environmental monitoring. These advancements are anticipated promote practical adoption SERS-based technology across diverse fields, suggesting broad future utility.
