A Portable Smartphone-Assisted Fluorescence Sensing Platform Based on Molecularly Imprinted Lanthanide MOF for Rapid Determination of Thiamethoxam in Vegetables

Thiamethoxam is a widely used neonicotinoid insecticide in agriculture, and its excessive use has raised growing concerns about food safety and environmental pollution. In this study, a portable fluorescence sensing platform was developed for the rapid detection of thiamethoxam by integrating a molecularly imprinted po...

Biphasic spatiotemporal regulation of Cas12a substrate cleavage enables one-pot autocatalytic CRISPR biosensing of non-nucleic-acid targets.

One-pot autocatalytic CRISPR biosensing offers a promising route for signal amplification without nucleic acid pre-amplification, but its efficiency is limited by an intrinsic readout-amplification conflict: the ssDNA reporter required for signal output competes with the autocatalytic mediator required for feedback amp...
