Wound healing is usually accompanied by bacterial infection. The excessive use of synthetic antibiotics leads to drug resistance, posing a significant threat human health. Hydrogel-based wound dressings aimed at mitigating infections have emerged as an effective treatment. review presented herein particularly focuses on the hydrogels originating from natural polymers. To further enhance performance dressings, various strategies and approaches been developed endow with excellent broad-spectrum antibacterial activity. Those that are summarized in current intrinsic or stimuli-triggered bactericidal properties others serve vehicles for loading agents without antibiotics. Specific attention paid antimicrobial mechanisms hydrogels. Practical applications accelerate employing these antibiotic-free also introduced along discussion challenges perspectives leading new technologies.

Although photothermal therapy (PTT) with the assistance of nanotechnology has been considered as an indispensable strategy in biomedical field, it still encounters some severe problems that need to be solved. Excessive heat can induce treated cells develop thermal resistance, and thus, efficacy PTT may dramatically decreased. In meantime, uncontrollable diffusion pose a threat surrounding healthy tissues. Recently, low-temperature (also known mild or mild-temperature PTT) demonstrated its remarkable capacity conquering these obstacles shown excellent performance bacterial elimination, wound healing, cancer treatments. Herein, we summarize recently proposed strategies for achieving based on nanomaterials introduce synthesis, characteristics, applications nanoplatforms. Additionally, combination other therapeutic modalities defeating cancers synergistic effect combined treatments are discussed. Finally, current limitations future directions inspiring more researchers make contributions promoting toward successful preclinical clinical disease

Bacteria-infected wounds are attracting increasing attention, as antibiotic misuse and multidrug-resistant bacteria complicate their treatment. Herein, we reported a photothermal activity-based drug consisting of β-cyclodextrin (βCD)-functionalized graphene oxide (GO) near-infrared light-responsive nanovehicles combined with the nitric donor BNN6, in methacrylate-modified gelatin (GelMA)/hyaluronic acid graft dopamine (HA-DA) hydrogel. The synergistic effects gas therapies expected to improve antibacterial efficiency reduce resistance. results revealed that GelMA/HA-DA/GO-βCD-BNN6 was an ideal material improved collagen deposition angiogenesis promoted wound healing mouse model full-thickness skin repair, compared commercially available Aquacel Ag dressing. We developed multifunctional nanocomposite hydrogel exhibited angiogenic properties, adhesiveness, mechanical properties enhance regeneration bacteria-infected wounds.

Bacterial infection has become one of the leading causes death worldwide, particularly in low-income countries. Despite fact that antibiotics have provided successful management bacterial infections, long-term overconsumption and abuse contributed to emergence multidrug resistant bacteria. To address this challenge, nanomaterials with intrinsic antibacterial properties or serve as drug carriers been substantially developed an alternative fight against infection. Systematically deeply understanding mechanisms is extremely important for designing new therapeutics.
