Zn‐MOF Encapsulated Antibacterial and Degradable Microneedles Array for Promoting Wound Healing

Advanced Healthcare Materials, Journal Year: 2021, Volume and Issue: 10(12)

Published: May 3, 2021

An infected skin wound caused by external injury remains a serious challenge in clinical practice. Wound dressings with the properties of antibacterial activity and potent regeneration capacity are highly desirable for healing. In this paper, degradable, ductile, wound-friendly Zn-MOF encapsulated methacrylated hyaluronic acid (MeHA) microneedles (MNs) array is fabricated through molding method promoting Due to damage capability against bacteria capsule oxidative stress zinc ion released from Zn-MOF, such MNs presents excellent activity, as well considerable biocompatibility. Besides, degradable composed photo-crosslinked MeHA possesses superior capabilities continuously steadily release loaded active ingredients avoid secondary wound. Moreover, low molecular weight (HA) generated hydrolysis also conducive tissue regeneration. Benefiting these features, it has been demonstrated that can dramatically accelerate epithelial neovascularization. These results indicate combination MOFs great value

Trilayer Metal–Organic Frameworks as Multifunctional Electrocatalysts for Energy Conversion and Storage Applications

Journal of the American Chemical Society, Journal Year: 2022, Volume and Issue: 144(8), P. 3411 - 3428

Published: Feb. 15, 2022

The need for enhanced energy storage and improved catalysts has led researchers to explore advanced functional materials sustainable production storage. Herein, we demonstrate a reductive electrosynthesis approach prepare layer-by-layer (LbL) assembled trimetallic Fe–Co–Ni metal–organic framework (MOF) in which the metal cations within each layer or at interface of two layers are linked one another by bridging 2-amino-1,4-benzenedicarboxylic acid linkers. Tailoring catalytically active sites an LbL fashion affords highly porous material that exhibits excellent trifunctional electrocatalytic activities toward hydrogen evolution reaction (ηj=10 = 116 mV), oxygen 254 as well reduction (half-wave potential 0.75 V vs reference electrode) alkaline solutions. dispersion-corrected density theory calculations suggest prominent catalytic activity MOF HER, OER, ORR is due initial negative adsorption water on nodes elongated O–H bond length H2O molecule.

Porphyrin-Containing MOFs and COFs as Heterogeneous Photosensitizers for Singlet Oxygen-Based Antimicrobial Nanodevices

ACS Applied Materials & Interfaces, Journal Year: 2021, Volume and Issue: 13(23), P. 26651 - 26672

Published: June 4, 2021

Visible-light irradiation of porphyrin and metalloporphyrin dyes in the presence molecular oxygen can result photocatalytic generation singlet (1O2). This type II reactive species (ROS) finds many applications where dye, also called photosensitizer, is dissolved (i.e., homogeneous phase) along with substrate to be oxidized. In contrast, metal-organic frameworks (MOFs) are insoluble (or will disassemble) when placed a solvent. When stable as suspension, MOFs adsorb large amount O2 photocatalytically generate 1O2 heterogeneous process efficiently. Considering immense surface area great capacity for gas adsorption MOFs, they seem ideal candidates this application. Very recently, covalent-organic (COFs), variants reticulation relies on covalent rather than coordination bonds, have emerged efficient photosensitizers. comprehensive mini review describes recent developments use porphyrin-based or porphyrin-containing COFs, including nanosized versions, photosensitizers toward antimicrobial applications.

Metal-polyDNA nanoparticles reconstruct osteoporotic microenvironment for enhanced osteoporosis treatment

Science Advances, Journal Year: 2023, Volume and Issue: 9(31)

Published: Aug. 2, 2023

Current clinical approaches to osteoporosis primarily target osteoclast biology, overlooking the synergistic role of bone cells, immune cytokines, and inorganic components in creating an abnormal osteoporotic microenvironment. Here, metal-polyDNA nanoparticles (Ca-polyCpG MDNs) composed Ca2+ ultralong single-stranded CpG sequences were developed reconstruct microenvironment suppress osteoporosis. Ca-polyCpG MDNs can neutralize osteoclast-secreted hydrogen ions, provide calcium repletion, promote remineralization, repair defects. Besides, immune-adjuvant polyCpG could induce secretion osteoclastogenesis inhibitor interleukin-12 reduce expression function effector protein inhibit differentiation, further reducing osteoclast-mediated resorption. PPi4- generated during rolling circle amplification reaction acts as bisphosphonate analog enhances targeting MDNs. In ovariectomized mouse rabbit models, prevented resorption promoted by restoring microenvironment, providing valuable insights into therapy.
