These nanofibers can be engineered for the controlled and sustained release of drugs, growth factors, and bioactive agents to improve treatment efficacy and mitigate side effects.

In tissue engineering, nanofibers serve as scaffolds that emulate the extracellular matrix and facilitate cell adhesion, proliferation, and differentiation, thus demonstrating the potential for regenerating tissues and organs, including bone, cartilage, and nerve repair. This review also explores their application in wound healing, where nanofiber dressings incorporating antimicrobial agents and growth factors can expedite healing, prevent infections, and minimize scarring, benefiting patients with chronic wounds, burns, and other complex skin injuries.

The pH of the gel formulations ranged from 5.35 to 7.40, the viscosity ranged from 3759 to 4710 cps, and the spreadability was adequate for topical application. Additionally, the optimized NS exhibited superior antifungal activity against Candida albicans and Aspergillus Niger, compared to drug alone and commercial fungicidal creams. Moreover, the in vitro studies confirmed the gel's effectiveness and its ability to sustain drug release, following Higuchi kinetics.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;The formulated CPO-loaded NS gels exhibit enhanced solubility, stability, and sustained drug release, significantly improving topical drug delivery with exceptional therapeutic efficacy. This novel approach underscores the potential of NSs for efficient and targeted medication delivery in both the pharmaceutical and cosmetic industries. Furthermore, their effective preparation method, excellent physicochemical properties, and antifungal activity make NSs a promising strategy for the oral delivery of poorly soluble drugs. The fungal skin infections are generally not serious but can be uncomfortable and persistent. With proper hygiene and appropriate treatment, most infections can be effectively managed. Therefore, understanding the types of fungi involved and recognizing symptoms early with an effective delivery system can lead to qu","PeriodicalId":19774,"journal":{"name":"Pharmaceutical nanotechnology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144049540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
