Article Synopsis
- A new combustion method was created to produce carbon and silver co-modified zinc oxide (ZnO) nanocomposites (NCs) to improve their effectiveness as photocatalysts.
- The study found that adding silver significantly boosts the photocatalytic activity, with an optimal Ag to Zn ratio of 2%, leading to a 150% increase in degradation rates under visible light compared to carbon-ZnO NCs, and a staggering 1233.3% improvement over pure ZnO.
- The presence of silver resulted in small particles (about 10 nm) on the surface of carbon-ZnO NCs, suggesting a collaboration between silver and carbon that enhances the photocatalytic performance when exposed to visible light.
A convenient, specific, and highly sensitive electrochemical immunosensor based on an indirect competitive assay format was developed for the determination of ochratoxin A (OTA), a common toxic contaminant in various kinds of agricultural products. The sensing substrate was prepared using a gold electrode modified with a self-assembled monolayer of 1,6-hexanedithiol that mediated the assembly of a gold colloid layer, which could enhance the surface loading of OTA-ovalbumin conjugate and improve the sensitivity in electrochemical readouts. After competition of the limited anti-OTA mouse monoclonal antibody between immobilized hapten and OTA analyte in sample solution, alkaline phosphatase (ALP)-labeled horse anti-mouse immunoglobulin G (IgG) antibody was selectively bound onto the surface of the electrode, affording an indicator for OTA concentration in the sample.
