AI Technical Summary

Technical Problem

Existing aquatic product testing technologies cannot achieve in-situ, pollution-free, and recyclable high-sensitivity testing. Furthermore, traditional equipment cannot be adapted to the irregular curved surfaces of aquatic products, resulting in low testing efficiency, unstable signal acquisition, and high costs.

Method used

A self-cleaning aquatic product testing sealing bag with a three-layer composite structure includes a food-grade plastic sealing film, a flexible PDMS substrate, and an ABD-MoS2 SERS detection layer. ABD-MoS2 nanosheets are prepared by a one-step CVD method, and combined with wet transfer and hot pressing processes to achieve curved surface adaptation and self-cleaning function.

Benefits of technology

It enables in-situ, highly sensitive detection of dye residues on the surface of aquatic products, with a detection limit as low as 10⁻⁸ M. The substrate can be recycled six times, reducing detection costs and avoiding cross-contamination.

Abstract

本发明公开一种自清洁型水产品检测密封袋及其制备方法和应用,涉及食品安全检测技术领域。该密封袋为三层复合结构,由食品级塑封膜、柔性PDMS基底和ABD‑MoS2 SERS检测层通过热压工艺一体化集成构成。采用CVD一步法制备ABD‑MoS2纳米片,通过优化湿法转移工艺将其稳定负载于PDMS基底,再与食品级塑封膜热压得到成品。制备得到的密封袋可紧密贴合水产品不规则曲面,实现目标物的原位吸附与检测,无需取样处理,操作简便。对亚甲基蓝等染料残留的检测限低至10‑8M,满足水产品残留检测的精度要求,且具备自清洁与循环使用性能,检测后经光照密封袋即可降解残留目标物,适用于直接接触水产品的检测场景。
