Multifaceted Catalytic Glucose Depletion and Reactive Oxygen Species-Scavenging Nanoenzyme Composite Hydrogel for Facilitating Diabetic Bone Regeneration

ACS Nano, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 9, 2025

Regeneration of diabetic bone defects remains a formidable challenge due to the chronic hyperglycemic state, which triggers accumulation advanced glycation end products (AGEs) and reactive oxygen species (ROS). To address this issue, we have engineered bimetallic metal–organic framework-derived Mn@Co3O4@Pt nanoenzyme loaded with alendronate Mg2+ ions (termed MCPtA) regulate microenvironment recover osteogenesis/osteoclast homeostasis. Notably, Mn atom substitution in Co3O4 nanocrystalline structure could modulate electronic significantly improve SOD/CAT catalytic activity for ROS scavenging. By integration GOx-like Pt nanoparticles, MCPtA achieved effective multiple cascade performance that facilitated clearance glucose ROS. Furthermore, was encapsulated within glucose-responsive hydrogel cross-linked via borate ester bond, termed PAM, evaluate potential composite cranial defect repair rats. The vitro/vivo experiments as well RNA sequencing analysis demonstrated disrupt glucose-ROS-induced inflammation promoted osteogenesis angiogenesis, consequence, improving therapeutic effects regeneration. This study provided crucial insights into nanoenzyme-mediated microenvironmental regulation

Synthesis and potential applications of cyclodextrin-based metal–organic frameworks: a review

Environmental Chemistry Letters, Journal Year: 2022, Volume and Issue: 21(1), P. 447 - 477

Published: Sept. 19, 2022

Abstract Metal–organic frameworks are porous polymeric materials formed by linking metal ions with organic bridging ligands. used as sensors, catalysts for transformations, biomass conversion, photovoltaics, electrochemical applications, gas storage and separation, photocatalysis. Nonetheless, many actual metal–organic present limitations such toxicity of preparation reagents components, which make unusable food pharmaceutical applications. Here, we review the structure, synthesis properties cyclodextrin-based that could be in bioapplications. Synthetic methods include vapor diffusion, microwave-assisted, hydro/solvothermal, ultrasound techniques. The diffusion method can produce framework crystals particle sizes ranging from 200 nm to 400 μm. Applications comprise packaging, drug delivery, adsorbents, membranes. Cyclodextrin-based showed loading efficacy bioactive compounds 3.29 97.80%.
