Colorimetric-SERS Dual-Mode Detection of Organophosphorus Pesticides Using Au-R-Fe3O4 Nanozyme Cascade Platform: A Practical Approach for Chemistry Education

Organophosphorus pesticides (OPs) pose significant environmental and health risks due to their persistence and neurotoxicity, yet current detection methods rely on sophisticated instrumentation inaccessible to educational settings. To address this pedagogical gap, we developed a recyclable Au-R-Fe3O4 nanozyme cascade...

Peroxide-like enzymes with fluorescent properties for colorimetric/fluorescent dual-mode detection and degradation of organophosphorus pesticide.

Organophosphorus pesticides (OPs) are widely used in modern agriculture to ensure crop yields; however, their high chemical stability and environmental persistence pose significant risks to human health and ecosystems through food chain bioaccumulation. Traditional detection methods, such as chromatography and immunoas...

Bifunctional chitosan-based fluorescent nanosensor for simultaneous detection and adsorptive removal of uranyl ions.

The widespread use and increasing consumption of uranium source in nuclear energy applications has led to inevitable environmental release of uranyl ions (UO22+), which accumulate through the food chain and pose severe risks to human health and ecosystem. Therefore, it is highly significant and desirable to develop a s...

Oxime-Functionalized Polydiacetylene Nanocomposite Sensor for Equipment-Free On-Site Detection Of Organophosphate Insecticide Chlorpyrifos Ethyl

A novel oxime-incorporated polydiacetylene-functionalized molecule (PCDA-OX) was synthesized for real-time, rapid, and selective detection of the organophosphate insecticide chlorpyrifos ethyl, which is widely used in agricultural fields globally. Nanocomposites containing PCDA-OX molecules were fabricated within a c...

Ag/CuTb2O2 nanozyme-based dual-mode biosensor with self-validating function for ultrasensitive detection of organophosphorus pesticides.

In this study, a dual-mode electrochemiluminescent-colorimetric (ECL-colorimetric) biosensor based on Ag/CuTb2O2 nanozyme was developed for the ultrasensitive detection of trichlorfon and other organophosphorus pesticides (OPs) by inhibiting acetylcholinesterase (AChE). The Ag/CuTb2O2 composite, prepared via electrospi...

An all-in-one Zn/Ce-MOF nanozyme: combining ratiometric sensing, oxidase-like activity, and apparent phosphoester hydrolase-like behavior for organophosphorus pesticide monitoring.

The widespread residue of highly toxic organophosphorus pesticides (OPs) poses a serious threat to food safety and human health, underscoring the need for sensitive screening methods. In this work, a ratiometric fluorescence sensor array was constructed based on a trifunctional Zn/Ce-MOF exhibiting intrinsic blue fluor...
