Here, Buchnania lanzan leaves serve as a renewable source of carbon. The obtained blackish brown CDs solution was centrifuged and the supernatant was filtered through syringe filter (0.22 µm). Further, the CDs solution was dried in vacuum oven to obtain powder. The synthesized CDs were characterized by different techniques including UV-Visible spectroscopy, fluorescence spectroscopy, fourier trans-form infrared (FTIR), zeta potential, x-ray diffraction (XRD). The as prepared CDs solution was found brownish colored in day light while exhibited green fluorescence under UV light. UV-Visible absorption spectrum displayed characteristic shoulder peaks of CDs at 257 nm and at 356 nm. In the fluorescence spectra, excitation dependent emission behaviour of CDs was seen, which is one of the distinct characteristics of CDs. The negative zeta potential and characteristic peaksin FTIR, suggested presence of carbonyl, amine and hydroxyl functional groups on the CDs surface. XRD spectrum exhibited broad peak at 2θ=19°, suggesting amorphous nature of CDs similar as reported in earlier works. As we have synthesized surface functionalized fluorescent carbon dots from a renewable and abundant precursor, this method can be highly useful in large scale synthesis of carbon dots with reduced costs and will find potential applications in the field of drug delivery,","PeriodicalId":11441,"journal":{"name":"ECSOC-25","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80092845","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}

Dev","doi":"10.3390/ecsoc-25-11664","DOIUrl":"https://doi.org/10.3390/ecsoc-25-11664","url":null,"abstract":": Invasive fungal infections require a long treatment schedule; however, treatment has become more cumbersome due to the development of resistance. Most antifungal moieties show systemic toxicity upon oral administration, leading to delivery of antifungal moieties via a topical route. Eberconazole (EBZ) is a BCS class II drug that has poor solubility and high permeability. It is a broad-spectrum imidazole derivative, which acts as a both fungicidal and fungistatic drug by inhibiting ergosterol synthesis. Various topical creams of EBZ are available in the market, but the lack of a proper dosing schedule and rapid removal lead to poor bioavailability. Niosomes are vesicular carriers that can entrap both hydrophilic and lipophilic drugs. Niosomal formulations have been prepared using Span20 (nonionic surfactant) and cholesterol by thin-ﬁlm hydration (TFH) technique. During preformulation studies, the purity of EBZ was ascertained using FT-IR and melting point studies, while the standard calibration curve was prepared using UV-visible spectroscopy. The prepared niosomal formulations were characterized for their morphology, entrapment efﬁciency, particle size, and zeta potential. The formulation has shown 86 ± 0.85% entrapment efﬁciency, while the noisome appeared in a ring-like structure during its microscopic evaluation. Further evaluations of in vitro and in vivo release studies will be performed in the future for its efﬁcacy and antifungal activity.","PeriodicalId":11441,"journal":{"name":"ECSOC-25","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87873277","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}
