To address these, SN-PB@PG nanocomplexes were prepared by hybridisation of nitroprusside (SNP) with Prussian blue (SN-PB NPs) and loaded with prodigiosin (PG). Under near-infrared (NIR) irradiation, SN-PB NPs generated mild hyperthermia, facilitating the release of nitric oxide (NO) and PG to combat bacterial biofilms and multidrug-resistant pathogens. The in vivo assay using diabetic infected wounds demonstrated that SN-PB@PG NPs with NIR reduced the wound area to 10.6% by the 11th day, which is superior to that of control group (29.6%). In the flap transplantation experiments, the data showed SN-PB@PG NPs with NIR group only have a necrobiosis of 3.8% of flaps on the 8th day, which is superior to 31.3% of the control group. Additionally, the release of NO promoted vascular regeneration by up-regulating vascular endothelial growth factor (VEGF) and platelet endothelial cell adhesion molecule-1 (CD31), and regenerated sarcomeric tissue by down-regulating MMP-9. The results indicated that the combination of SN-PB@PG NPs with gas and photothermal therapy exerted a combined antibacterial and wound healing effect. Compared to traditional clinical methods such as surgical debridement and hyperbaric oxygen therapy, this new strategy efficiently addresses issues of infection and healing, which is convenient for clinical application.</p>","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":" ","pages":"e2405100"},"PeriodicalIF":10.0,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This perspective hypothesizes that nanoscale surface topography can impact on the topology of cancer cells network under radiation, and that this understanding can possibly advance the assessment of cell radio-resistance in RT applications. An experimental plan is proposed to test this hypothesis, using cancer cells exposed to various RT forms. By examining the influence of 2D surface and 3D scaffold nanoscale architecture on cancer cells, this approach diverges from traditional methodologies, such as clonogenic assays, offering a novel viewpoint that integrates fields such as tissue engineering, artificial intelligence, and nanotechnology.

However, when inflammation fails to resolve and restore basal homeostasis, it can lead to various inflammatory diseases such as rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and diabetic chronic wound (DCW). The modulation of inflammation follows a highly complex mechanism, and monotherapy is often insufficient for treating such conditions. Therefore, developing next-generation nanocarriers for anti-inflammatory drug delivery and multi-target combination therapies is critical. Metal-organic frameworks (MOFs), a class of porous coordination polymers with large surface areas and adaptable porosity, have emerged as promising drug delivery systems (DDS) due to their biodegradability, high drug loading capacity, stimuli-responsive drug release, and ease of functionalization. Over the past five years, MOFs have shown significant promise in treating inflammatory diseases, either as DDS or as intrinsic anti-inflammatory and anti-oxidative agents. Additionally, hybrid MOFs, which combine MOFs with nanozymes, offer a multifunctional anti-inflammatory platform with great potential.

Considering the low-pH microenvironment following HSV-1 infection, a pH-responsive baicalein@chitosan (B@C) hydrogel is developed for the topical treatment of HSV-1 skin infections. This hydrogel is synthesized by incorporating baicalein, a natural flavonoid, into a chitosan matrix modified with 4-formylphenylboronic acid and protocatechualdehyde to achieve potent anti-HSV-1 activity and pH-responsiveness. In vitro results demonstrated the hydrogel's pH-dependent inhibitory effect on HSV-1 infections, including ACV-resistant strains.

Ultra-high-performance liquid chromatography-tandem mass spectrometry analysis revealed a sustained release of baicalein from the hydrogel, ensuring long-term drug retention in HSV-1-infected skin tissues.
