Neonicotinoid insecticides have been widely applied in modern agriculture to improve crop productivity, but their residues adverse impacts on the environment and human health. Hence, address these issues, a portable self-powered/colorimetric dual-mode sensing platform was developed for simple, rapid, precise, sensitive on-site detection of acetamiprid (ATM) vegetables. In this case, multifunctional bioconjugate with specific recognition capability, excellent enzyme-like activity, loading capacity is key design. Using an Eppendorf (EP) tube as miniaturized laboratory, bioconjugates colorimetric test strip were integrated into EP tube, combined nanozyme-based self-powered (with area 1.5 × cm2), accurate ATM achieved, limits low 2.9 fg·mL–1 (self-powered method) 31.5 (colorimetry), respectively. Notably, we simulated actual insecticidal situation based field application concentration quantified pesticide The relative errors our method standard high-performance liquid chromatography 0.15% (the 1.8% high sensitivity accuracy opened up new avenue development residue analysis next generation agricultural products.

Excessive use of antibiotics in aquaculture severely endangers human health and ecosystems, which has raised significant concerns recent years. However, conventional laboratory-based approaches regularly required time or skilled manpower. Herein, we propose a point-of-care-testing (POCT) biosensor detection device for the simultaneous determination multiantibiotics without complex equipment professional operators. A laser-printed paper-based microfluidic chip loaded with multicolor fluorescence nanoprobes (mCD-μPAD) was developed to rapidly detect sulfamethazine (SMZ), oxytetracycline (OTC), chloramphenicol (CAP) on-site. These "fluorescence off" probes composed carbon dots (CDs) conjugated aptamers (donor) MoS2 nanosheets (acceptor) (CD-apt-MoS2) were based on Förster resonance energy transfer. Upon addition target antibiotics, significantly recovered signal μPAD can be sensitively perceived by employing 3D-printed portable box through smartphone. Under optimal conditions, this allowed rapid response 15 min toward SMZ, OTC, CAP considerable sensitivities 0.47, 0.48, 0.34 ng/mL, respectively. In shrimp samples, recoveries 95.2–101.2, 96.4–105, 96.7–106.1% RSD below 6%. This sensor opens an avenue on-site, high-throughput, methods widely used POCT food safety.
