Summary: Electrochemical aptamer-based sensors (EABs) have been demonstrated to have sensitivity and specificity for multiple analytes in vivo. However, their longevity is limited to 24 hours and they lack sensitivity for highly dilute analytes. A new approach using aptamers freely mobile in solution has been proposed to improve longevity and sensitivity. The solution-phase EAB sensor showed promising results, but further development is needed for long-lasting continuous sensing applications.

Summary: In this work, uniform plasmonic Au nanobipyramids@Ag nanorods (Au NBP@Ag NR)-CsPbX3 films with strong surface-enhanced Raman scattering (SERS) activity were constructed for the sensitive and multiple detection of veterinary drug residues. CsPbI3 quantum dots (QDs) with large dielectric constant and plasmon-induced metal-to-perovskite interfacial charge transfer transition contributed to the SERS enhancement. The SERS-active films exhibited excellent sensitivity and reproducibility for the quantitative and accurate detection of chloramphenicol, diazepam and malachite green in food matrix.
