Prussian‐Blue Catalysis and NFC Synergy: a Battery‐Free Laser‐Induced Graphene‐Based Platform for Urine Glucose Monitoring at Point‐of‐Care

open access: yesAdvanced Science, Volume 12, Issue 20, May 29, 2025.
In this study, Merkoçi and his research group present a polymer‐based synthesis to enhance the stability of Prussian blue (PB) nanoparticles. The resulting PB‐infused catalytic hetero‐interface architecture (PB‐CHIA) achieves complete two‐dimensional (2D) and three‐dimensional (3D) substrate coverage (glassy carbon and laser‐induced graphene electrodes)

Tuning the Sensitivity of Photonic Sensors Toward Alkanes Through the Textural Properties of Hybrid Xerogel Coatings

open access: yesAdvanced Functional Materials, Volume 35, Issue 3, January 15, 2025.
A propylsilane molar content of just 5% makes a poor‐responding silica xerogel film to become sensitive toward non‐aromatic, large volatile organic compounds with low or null polarity when assembled into a photonic sensor with reflection architecture. This device is particularly suitable to detect cyclohexane, with large signal variation, fast kinetics,
