Discovery of Surface‐Induced Resonance Shift of 4‐Nitrophenol Enabling Direct Monitoring of an Enzymatic Reaction

open access: yesAdvanced Sensor Research, Volume 4, Issue 10, October 2025.
A surface‐modified porous silica consisting of acetyl‐protected mannose residue and co‐precipitated urea compounds promotes a distinct resonance shift of 4‐nitrophenol under neutral conditions upon interaction, that is revealed by confocal Raman spectroscopy. The quinone‐type resonance structure is favored over the phenol‐type.

Adaptive Antioxidant Nanomedicines Inhibit Ferroptosis in Renal Tubular Epithelial Cells to Alleviate Diabetic Kidney Disease

open access: yesAdvanced Science, Volume 12, Issue 37, October 6, 2025.
In this study, an adaptive antioxidant nanodrug (AAN) is developed through the self‐polymerization of L‐selenocysteine. The AAN exhibits dual functionalities: antioxidant activity (scavenging reactive oxygen species) and mitochondrial targeting. Moreover, the released selenium (Se) participates in the synthesis of glutathione peroxidase 4 (GPX4), which
