Thermoresponsive Hydrogel‐Enabled Thermostatic Photothermal Therapy for Enhanced Healing of Bacteria‐Infected Wounds

Advanced Science, Journal Year: 2023, Volume and Issue: 10(11)

Published: Feb. 12, 2023

Abstract Photothermal therapy (PTT) has emerged as an attractive technique for the treatment of bacterial infections. However, uncontrolled heat generation in conventional PTT inevitably causes thermal damages to healthy tissues and/or organs. It is thus essential develop a smart and universal strategy regulate photothermal equilibrium temperature preset safe threshold. Herein, thermoresponsive hydrogel‐enabled thermostatic system enhanced healing bacteria‐infected wounds reported. In this system, near‐infrared (NIR)‐triggered by nanomaterials spontaneously transferred hydrogel with lower critical solution (LCST), leading its rapid phase transition forming considerable light‐scattering centers block NIR penetration. Such dynamic reversible process automatically regulates phase‐transition point LCST‐type hydrogel. contrast temperature‐uncontrolled severe damages, provides effective protection on organs, which remarkably accelerates wound efficient eradication. This study establishes smart, simple platform, holding great promise skin

An Immunoregulation Hydrogel with Controlled Hyperthermia‐Augmented Oxygenation and ROS Scavenging for Treating Diabetic Foot Ulcers

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(33)

Published: May 6, 2024

Abstract Diabetic foot ulcers (DFUs), a serious and increasingly common chronic issue among diabetics, often do not respond well to generalized treatment strategies. Hypoxia the overexpression of reactive oxygen species (ROS), resulting in inflammatory dysregulation subsequent imbalance macrophage phenotypes, are critical factors contributing prolonged non‐healing DFU wounds. These two issues interact continuous, problematic cycle. Presently, there is lack comprehensive strategies aimed at addressing both these simultaneously interrupt this detrimental Herein, an immunomodulatory hydrogel (PHG2) developed for reshaping hostile microenvironment. The engineered PHG2 only removes excess internally‐produced ROS but also generates O 2 , with its efficiency further boosted by local hyperthermia (42.5 °C) activated near‐infrared light. Through vitro vivo studies, along transcriptomic assessment, it confirmed that disrupts feedback loop between inflammation while lowering M1/M2 ratio. Such discoveries contribute significant enhancement healing process injuries undergo gradual increase movement, covering wounds from back, mouth, foot. Ultimately, method provides easy, safe, highly effective solution treating DFUs.

Development of an Antiswelling Hydrogel System Incorporating M2-Exosomes and Photothermal Effect for Diabetic Wound Healing

ACS Nano, Journal Year: 2023, Volume and Issue: 17(21), P. 22106 - 22120

Published: Oct. 30, 2023

Diabetic wounds represent a persistent global health challenge with substantial impact on patients' and overall well-being. Herein, hydrogel system that integrates functionalized gold nanorods (AuNRs) M2 macrophage-derived exosomes (M2-Exos) was developed to achieve an efficient synergistic therapy for diabetic wounds. We introduced ion-cross-linked dissipative network into prefabricated covalent cross-linked (long-chain polymer network), which prepared using AuNRs as specific cross-linker. The ion then the long-chain in situ form structure, imparting antiswelling photothermal effects hydrogel. This integrated effectively scavenged reactive oxygen species levels, inhibited inflammation, promoted angiogenesis, stimulated antibacterial activity through near-infrared (NIR) irradiation. To demonstrate potential of hydrogel, we established experimental animal models oral mucosa ulceration full-thickness skin defects. In vivo results confirmed M2-Exos released from hydrogels played crucial role wound closure. Furthermore, effect NIR eradicated bacterial infections area. Overall, our is promising tool accelerating chronic healing tissue regeneration. study highlights benefits combining bioactive platform satisfactory patients diabetes.

Angewandte Chemie International Edition, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 5, 2025

Abstract Infectious diseases pose considerable challenges to public health, particularly with the rise of multidrug‐resistant pathogens that globally cause high mortality rates. These can persist on surfaces and spread in healthcare settings. Advances have been made developing antimicrobial materials reduce transmission pathogens, including composed naturally sourced polyphenols their derivatives, which exhibit potency, broad‐spectrum activity, a lower likelihood promoting resistance. This review provides an overview recent advances fabrication phenolic biomaterials, where natural compounds act as active agents or encapsulate other (e.g., metal ions, peptides, biopolymers). Various forms biomaterials synthesized through these two strategies, particles, capsules, hydrogels, coatings, are summarized, focus application wound healing, bone repair regeneration, oral coatings for medical devices. The potential advanced promising therapeutic approach combating antimicrobial‐resistant infections reducing microbial transmission.
