TL;DR: The detecting results of pesticide residues in food samples via this method agree well with those from high-performance liquid chromatography and should be suitable for on-site pesticides detection, especially in combination with other portable platforms.

TL;DR: A protein-directed co-template strategy to synthesize a NIR-based, dual-emission fluorescent nanohybrid (DEFN) constructed from far-red gold nanoclusters and NIR PbS QDs (AuNCs-PbS-QDs) is proposed, enabling the proposed DEFN to ratiometrically detect AA.

TL;DR: A label-free fluorometric sensor for Cu(2+) sensing was developed based on the unique multivalent metal ion-binding property of H39GFP and fluorescence quenching effect of Cu( 2+) by electron transfer.

TL;DR: An aptamer-based quartz crystal microbalance (QCM) biosensor was developed for the selective and sensitive detection of leukemia cells, and both the QCM and fluorescence microscopy results manifested the selectivity of the sensor designed.

TL;DR: The sgc8c aptamer-conjugated MBs specifically binding to CCRF-CEM cells were used for target cell extraction from complex matrixes, and the magnet-QCM system was successfully applied for quantitative cell detection, requiring no further labeling of cells.
