Antioxidant‐Thermoresponsive Collagen/Chitosan Nanocomposite Hydrogels With Praseodymium‐Doped Mesoporous Bioglass for Enhanced Bone Regeneration

open access: yesJournal of Biomedical Materials Research Part A, Volume 114, Issue 9, September 2026.
ABSTRACT Oxidative stress is a critical barrier to effective bone regeneration, often impairing cellular function and osteogenic differentiation. In this study, we report the novel development of a multifunctional chitosan/collagen (CS/Coll) hydrogel integrated with praseodymium‐doped mesoporous bioactive glass nanoparticles (Pr‐MBGNs) engineered for ...

Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors

open access: yesAdvanced Materials, Volume 38, Issue 47, 21 August 2026.
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...
