3D‐Printed Metal‐Supported MOF‐Heteropoly Acid Nanozyme for High‐Performance Peroxidase‐Mimic Activity and Ultra‐Sensitive Glucose Detection

open access: yesAdvanced Science, EarlyView.
A hierarchically structured Fe‐BTC‐PMA immobilized 3D‐printed platform is engineered as a robust artificial enzyme for colorimetric glucose sensing. The hybrid architecture efficiently activates H2O2 to drive TMB oxidation. This integrated system enables sensitive, reusable, and scalable detection with enhanced catalytic stability and analytical ...

Grape Seed Polyphenols Enhance Antioxidant Activity and Prolong the Lifespan of Caenorhabditis elegans Through SKN‐1/Nrf2 Pathway

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
GSP extends C. elegans lifespan, enhances stress resistance and reproduction, boosts antioxidant defenses (↑SOD/CAT/GSH‐Px, ↓ROS), remodels glycolysis/TCA/one‐carbon metabolism dose‐dependently, and activates SKN‐1/Nrf2 and H3K4 methylation—linking redox control to epigenetic modulation.
