Glucose detection is critical for diabetes diagnosis and management. This study aimed to develop an enzyme-free, cascade-based, triple-readout paper sensor utilizing bismuth (Bi)-based metal-organic frameworks/gold nanoparticles (Bi-BDC-NH@Au) for detecting urine glucose. Herein, Bi-BDC-NH@Au exhibited glucose oxidase-like activity and oxidized glucose to generate HO, which then quenched the blue fluorescence of FP@Bi-BDC-NH@Au through an inner filter effect.

- The improper use of organophosphate pesticides (OPs) can create harmful residues that endanger human health and the environment, necessitating effective detection methods.
- A new all-in-one paper-based sensor was developed using a bioenzyme-nanozyme-chromogen system, integrated with a Python-based image recognition algorithm for detecting OPs.
- This sensor demonstrated strong detection capabilities, identifying di-chlorovinyl dimethyl phosphate (DDVP) with a limit of 0.32 ng/mL and a recovery rate between 95-107%, making it applicable for on-site testing in fruits and vegetables.
Ribavirin (RBV) that is not metabolically released into the environment can contaminate the environment and even make organisms resistant to it. Therefore, it is of great significance to establish a simple and effective method for adsorbing RBV in the environment. In this study, a novel biochar-based boronate affinity molecularly imprinted polymers (C@H@B-MIPs) were synthesized.
