An innovative polymer-based dual detection microfluidic platform has been developed for the accurate and reliable sensing of trace amounts antibiotic tetracycline in environmental food samples. This was achieved through production a bespoke polymeric material formed via an imprinting technique using fluorescent dye. Thus, this enables tetracycline, both thermally, analyzing heat-transfer resistance at solid-liquid interface, optically, inner filter effect. The combination these two methods nanomolar limit while also providing rapid, selective, cost-effective sensing. Additionally, method successfully detected levels 0.56 μM blank egg samples which significantly lower than maximum residual level 400 μg L-1 (0.9 μM). Our work shows that approach can be used efficient antibiotics complex samples, offering enhanced reliability integration complementary analysis techniques. sensor potential to identify sources antimicrobial resistance, is crucial targeted efforts combat pressing global health challenge.
