Although surgery, chemotherapy, and radiation therapy are common treatments, they carry significant risks to healthy cells. The versatile benefits of using lipid-based nanocarrier systems in healthcare, combined with the therapeutic and supportive properties of micronutrients like selenium, have led to the investigation of encapsulating selenium nanoparticles in liposomes (Lip-SeNPs) as a new therapeutic strategy. Using scanning electron microscope-energy dispersive X-ray spectroscopy (SEM-EDS), dynamic light scattering (DLS), X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR), the characterisation and stability of the Lip-SeNPs were compared with liposome-free SeNPs. This was followed by their cytotoxicity evaluation against lung cancer cells. The DLS results showed that the synthesised liposome-free SeNPs and Lip-SeNPs were spherical, with size distribution of around 151.2 and 163 nm. The zeta potential values were determined for Lip-SeNPs (-15.7 mV) compared to liposome-free SeNPs (-5.71 mV). FTIR analysis of SeNPs and Lip-SeNPs confirmed valuable information about their surface chemistry and potential structure functionalisation avenues. The augmented results obtained from DLS (homogenous size distribution), Zeta potential (higher negative charge), XRD (no other element interference), and SEM-EDS (53 % selenium encapsulation and negligible agglomeration) further strengthened the stability of the generated Lip-SeNPs compared to liposome-free SeNPs. Furthermore, 74.62 % of the SeNP encapsulation efficiency in liposomes was achieved in this study. In addition, dialysis membrane-based drug release profile studies revealed augmented acidic pH-responsive release profiles of Lip-SeNPs, suggesting a superior bioavailability for drug delivery against lung cancer cells.</div></div>","PeriodicalId":100959,"journal":{"name":"Next Nanotechnology","volume":"7 ","pages":"Article 100121"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143146335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This property makes siRNA a valuable tool for developing RNAi therapeutics, particularly for managing conditions like osteoporosis, cancer, genetic disorders, and autoimmune disorders. Rheumatoid arthritis (RA) is a significant autoimmune disorder. Several treatments are available for RA, including analgesics, corticosteroids, DMARDs, biological agents, combinational therapy, epigenetic and cell therapies which play a crucial role in preventing joint function deterioration, inflammation, synovial edema, etc. Besides these numerous advantages, these treatments have several disadvantages like liver cirrhosis, interstitial lung disease, sexual health is impaired in males, neuropsychiatric adverse effects, etc. All these disadvantages engender the need for new therapy. siRNA delivery carriers like liposomes, polymeric nanoparticles, and siRNA polymer bio-conjugates are proving to be particularly effective with less toxicity compared to the traditional treatments. A promising addition to these carriers is wrapsome (WS), which can be used as a favorable carrier for delivery of siRNA to its specific sites, such as inflamed joints or the inflamed synovium. The incorporation of PEG liposomes in the delivery strategy allows WS to evade recognition by the RES, leading to an extended half-life.

The comprehensive analysis include methods for producing nanofibers, crucial design components, and applications appropriate for different wound types. Concurrently, the integration of the Internet of Things (IoT), Artificial Intelligence (AI), and Machine Learning (ML) is revolutionizing wound care. Because of this, \"smart\" dressings with real-time monitoring, dynamic data processing, and precise therapeutic release capabilities have been developed, allowing medical personnel to provide more individualized and responsive care. These developments can potentially revolutionize wound care through timely interventions and improving patient outcomes. Although combining nanofiber technology with AI-powered smart dressings seems promising, there are still barriers in implementing these developments for general clinical applications. This review offers a comprehensive overview of current research and the critical role nanofiber technology plays in enhancing wound care. We plan to highlight the path for robust, scalable, and customized wound treatments by identifying key implementation barriers and exploring potential developments. Nanofibers, with their exceptional capabilities, signify a profound advancement in wound healing, offering new optimism for improved patient recovery and enduring health benefits.</div></div>","PeriodicalId":100959,"journal":{"name":"Next Nanotechnology","volume":"8 ","pages":"Article 100147"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143551421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
