Dual-mode electrochemiluminescence and colorimetric detection of malathion based on a bifunctional rGO@ZnO/Zn-Fe3O4 nanozyme

Dual-mode colorimetric and RGB detection of sulfide based on a magnetic Fe3O4/CoFe2O4/Ce-BDC hybrid nanozyme

A dual-mode sensing strategy is presented by integrating a magnetic Fe3O4/CoFe2O4/Ce-BDC (denoted as FCF/Ce-BDC) nanozyme with TMB/H2O2 chromogenic chemistry to construct peroxidase-mimetic hybrids. The FCF/Ce-BDC catalyst efficiently oxidizes 3,3’,5,5’-tetramethylbenzidine (TMB) in the presence of hydrogen peroxide (H...

Au@NiMnO3@g-C3N4-based electrochemiluminescence immunosensor for sensitive procalcitonin assay via quenching by tungsten-based polyoxometalate nanoclusters.

A dual-mode electrochemical-colorimetric sensor based on Cu-MoSe2@AuNPs nanozyme assembly for the determination of ochratoxin A in food

Smartphone-assisted colorimetric sensor coupled with magnetically recoverable MnFe2O4/ZnO/rGO nanocomposites for trace detection and photocatalytic removal of tetracycline antibiotics.

In this work, a MnFe2O4/ZnO/rGO nanocomposite was successfully synthesized and explored for dual applications in photocatalytic degradation and colorimetric detection of tetracycline (TC) antibiotics. The structural, optical, and morphological analyses confirmed the formation of well-integrated heterostructures, featur...

A dual-quenching electrochemiluminescence immunosensor based on ABEI@Fe3O4@PDA-PdPt and Cu2−xS nanoflowers for sensitive detection of galectin-3

This work presents a novel strategy for the highly sensitive detection of Gal-3, leveraging the synergistic dual-quenching mechanism to achieve excellent analytical performance, thereby holding significant promise for clinical diagnostics and early disease monitoring applications.

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...
