Colorimetric sensors and biosensors exhibit promising potential toward the detection of
metallic cations, anions, organic dyes, drugs, pesticides and other toxic pollutants due to …

The traditional sensors are designed based on the “lock-and-key” strategy with high
selectivity and specificity for detecting specific analytes, which however are not suitable for …

Most organophosphorus pesticide (OP) sensors reported in the literature rely on the
inhibition effect of OPs on the activity of acetylcholinesterase (AChE), which suffer from the …

Sensors for pesticides with high sensitivity have been urgently required to control food
safety, protect ecosystem and prevent disease. In this review, we provide an overview of …

Pesticides, widely used for pest control and plant growth regulation, have posed a threat to
the environment and human health. Conventional methods to analyze pesticide residues …

Noble metal nanoparticles (NPs) are ideal scaffolds for the fabrication of sensing devices
because of their high surface-to-volume ratio combined with their unique optical and …

Carbon dots (CDs) combined with a nanomaterial-based quencher has created an
innovative way for designing promising sensors. Herein, a novel fluorescent-sensing …

A sensor array based on the pattern recognition strategy is good at distinguishing subtle
changes of extremely similar mixtures over a wide range of analyte types. Particularly …

Paper-based analytical devices (PADs) have shown great promise for point-of-care testing
and on-site detection of analytes with chemical, biochemical, and environmental importance …

The nanoparticle colorimetric‐based methods have been extensively used for rapid
detection, however there are few limitations which can be kept under control or avoided by …
