Perfluorooctanoic acid (PFOA) poses a threat to the environment and human health due to
its persistence, bioaccumulation, and reproductive toxicity. Herein, a lanthanide metal …

Fluorescent metal–organic frameworks (MOFs) are promising sensing materials with tunable
and robust structural properties and remarkable luminescent capabilities. In this study, a …

This study aims to develop a cheap method for the evaluation of quality of water or the
assessment of the treatment of water by chemical oxygen demand (COD) measurements …

Herein, a strategy combining colorimetry and inner filter effect (IFE)-based fluorometry was
developed for multimode visualization of food dyes (FDs) using CdTe quantum-dots-doped …

Herein, a robust instrument-free point-of-care tests (POCTs) strategy was proposed for rapid
naked-eye detection of artificial food colorants (AFCs) using filter paper as a sampling and …

Abstract Nitrite (NO 2−) is widely present in the natural environment and human daily life.
Excessive NO 2− can cause harm to the environment and human health. Herein, silicon …

The measurement of fluorescence emission for quantitative analysis is typically based on a
traditional spectrofluorometer, which limits an onsite detection approach. Thus, an …

A new hybrid biological-chemical catalyst, magnetic nanoparticles functionalized with
cholesterol oxidase (Fe 3 O 4/APTES/ChOx), was developed for cholesterol detection. In the …
