Abstract

Flexible surface-enhanced Raman scattering (SERS) sensors show promise for non-destructive, on-site fruit quality monitoring; however, current SERS substrates frequently fail to meet the extended operational stability demands of cross-seasonal agricultural storage systems. This study presents a durable, recyclable, and stretchable plasmonic film (Au@AgNWs/PDMS) for decay detection in grapefruits. By partially embedding silver nanowires (AgNWs) in PDMS and functionalizing surfaces with gold nanoparticles via galvanic replacement, the composite film achieves high sensitivity (10⁻⁹ M rhodamine 6G), mechanical resilience (85% tensile strain tolerance), and long-term stability (49 days). The substrate retains stable SERS performance through 1000 stretching cycles and supports five regeneration cycles without degradation. Practical validation demonstrated its capacity for in situ fungal biomarker tracking on grapefruit surfaces, correlating quinone accumulation with decay progression. Combining conformal adhesion, environmental resistance, and reusability, this technology offers a scalable solution for enhancing food security during storage.

耐用，可回收，可拉伸的等离子体膜葡萄柚腐烂检测。

柔性表面增强拉曼散射（SERS）传感器有望用于非破坏性的现场水果质量监测；然而，目前的SERS基板往往不能满足跨季节农业储存系统的扩展运行稳定性需求。这项研究提出了一种耐用、可回收、可拉伸的等离子体膜（Au@AgNWs/PDMS），用于葡萄柚的腐烂检测。通过在PDMS中部分嵌入银纳米线（AgNWs）并通过电替换将金纳米粒子功能化表面，复合膜具有高灵敏度（10 - 9 M罗丹明6G），机械弹性（85%的拉伸应变容量）和长期稳定性（49天）。通过1000次拉伸循环，基材保持稳定的SERS性能，并支持5次再生循环而不降解。实际验证表明，它能够在葡萄柚表面进行真菌生物标志物的原位跟踪，将醌积累与腐烂进程联系起来。结合保形附着力，环境抗性和可重用性，该技术为提高储存期间的食品安全提供了可扩展的解决方案。
