AI Technical Summary
In existing technologies, the poor solubility of MOF crystals leads to uneven dispersion in analyte solutions, affecting sensitivity and accuracy. Furthermore, they are difficult to recover, limiting the sensitivity and recyclability of fluorescence detection and making it difficult to achieve portable, real-time on-site detection.
MOFs crystals are uniformly dispersed in a polymer matrix to prepare MOFs-based hybrid matrix membranes. Combining the flexibility and mechanical stability of the polymer, on-site visual quantitative detection is performed with the assistance of a smartphone.
This invention achieves portability, ease of operation, fast detection speed, and convenient recovery of MOFs-based hybrid matrix membranes, enabling on-site visual quantitative detection of acetamiprid, and improving the sensitivity and accuracy of detection.
