Capitalizing on its high peroxidase-like activity, we developed a colorimetric assay for detecting hydrogen peroxide (H2O2) and glucose, which exhibited high stability, sensitivity, and accuracy in biological samples such as serum....Furthermore, by leveraging the reversible structural dynamics of Fc(COOH)2-PBA, we engineered a dual-mode colorimetric assay for visual quantitation of H2O2 and glucose in complex samples, including cells, tissues, and cerebrospinal fluid.

Our objective was to develop a simple, low-cost colorimetric assay to detect kynurenine (L-Kyn) in human biofluids, that would be compatible with a point-of-care (POC) system being developed in our lab. Elevated L-Kyn is associated with many pathological conditions....Here we report a two-step diazotization-based colorimetric assay that produces a red chromophore upon reaction with L-Kyn. To reduce background interference, we used dilution and anion exchange chromatography for urine samples and acid precipitation for serum samples.

Comparison to a widely used colorimetric assay demonstrated that the results of the two methods differ if applied to soluble fiber samples.
A QCM-D-based continuous assay for the study of the enzymatic degradation of insoluble calcium-polygalacturonate [0.03%]
基于QCM-D的连续测定法用于研究不可溶性钙-多半乳糖醛酸聚糖的酶降解作用

We show that the enzymatic rates respond in a dose-dependent manner to the frequency increase during QCM-D measurements and demonstrate that such an assay can detect enzyme attack characteristics that a colorimetric assay using soluble polygalacturonic acid cannot.
