Humans are threatened by bacteria and other microorganisms, resulting in countless pathogen-related infections illnesses. Accumulation of reactive oxygen species (ROS) infected wounds activates strong inflammatory responses. The overuse antibiotics has led to increasing bacterial resistance. Therefore, effective ROS scavenging bactericidal capacity essential the advanced development collaborative therapeutic techniques combat is needed. Here, this work developes an MXene@polydopamine-cryptotanshinone (MXene@PDA-CPT) antibacterial nanosystem with excellent nitrogen ability, which effectively inactivates drug-resistant biofilms, thereby promoting wound healing. In system, adhesion polydopamine nanoparticles MXene produced a photothermal synergistic effect free radical activity, presenting promising anti-inflammatory strategy. This causes fatal damage membranes. loading cryptotanshinone further expanded advantages causing stronger killing inflammation mitigatory desired biosafety biocompatibility. addition, combining nanomaterials active ingredients traditional Chinese medicine, provides new rationale for future dressings, contributes eliminating resistance, delaying disease deterioration, alleviating pain patients.

In diabetic patients with skin injuries, bacterial proliferation, accumulation of reactive oxygen species (ROS) in the tissues, and impaired angiogenesis make wound healing difficult. Therefore, eliminating bacteria, removing ROS, promoting are necessary for treating acute wounds. this study, benefiting from ability polyphenols to form a metal-phenolic network (MPN) metal ions, TA-Eu MPN nanoparticles (TM NPs) were synthesized. The prepared photothermal agent CuS NPs TM then loaded onto supporting base needle tips PVA/HA (PH) microneedles, respectively, obtain PH/CuS/TM microneedles. Antibacterial experiments showed that microneedles could remove bacteria by effect. vitro effectively scavenge inhibit macrophage polarization M1 type, induce M2 type as well have promote vascular endothelial cell migration angiogenesis. Furthermore, vivo accelerated inhibiting pro-inflammatory cytokines rat model. efficient antibacterial, ROS scavenging, anti-inflammatory, immunomodulatory, angiogenic abilities hold promise dressings

Metal–Phenolic Networks‐Reinforced Extracellular Matrix Scaffold for Bone Regeneration via Combining Radical‐Scavenging and Photo‐Responsive Regulation of Microenvironment

Advanced Healthcare Materials, Год журнала: 2024, Номер 13(15)

Опубликована: Фев. 7, 2024

Abstract The limited regulation strategies of the regeneration microenvironment significantly hinder bone defect repair effectiveness. One potential solution is using biomaterials capable releasing bioactive ions and biomolecules. However, most existing lack real‐time control features, failing to meet high requirements. Herein, a new Strontium (Sr) epigallocatechin‐3‐gallate (EGCG) based metal–phenolic network with polydopamine (PMPNs) modification prepared. This material reinforces biomimetic scaffold made extracellular matrix (ECM) hydroxyapatite nanowires (nHAW). PMPNs@ECM/nHAW demonstrates exceptional scavenging free radicals reactive oxygen species (ROS), promoting HUVECs cell migration angiogenesis, inducing stem osteogenic differentiation, displaying biocompatibility. Additionally, PMPNs exhibit excellent photothermal properties, further enhancing scaffold's bioactivities. In vivo studies confirm that near‐infrared (NIR) stimulation promotes angiogenesis osteogenesis, effectively regulating facilitating tissue repair. research not only provides for but also introduces novel strategy designing advanced biomaterials. combination intervention long‐term chemical intervention, achieved through release molecules/ions, represents promising direction future biomaterial development.
