The versatility of NPs applications partly arises from the possibility of manufacturing various NPs types depending on the nature of starting materials. In most cases, amphiphilic materials such as phospholipids, solid lipids, fatty acid derivatives, and blends of oils/surfactants, are used to make distinct NPs, namely liposomes, solid lipid nanoparticles (SLNs), nanostructured lipid carriers (NLCs), micelles, and nanoemulsions, respectively. In the pipeline of raw materials, saponins have emerged as a promising alternative for NPs formulation. Saponins are plant-derived secondary metabolites (phytochemicals) with excellent amphiphilic properties, which allow them to play crucial roles in nanotechnology, including their usage as reagents for micellar preparation as well as stabilizing agents for several NPs. Saponin-based NPs have been used to improve the solubility, and pharmacological profile of various active ingredients, encompassing vaccines, owing to inherent immunostimulant/adjuvant properties of saponins. In this review, we mainly discuss the state of the art in biomedical and pharmaceutical applications of saponin-containing NPs, focusing on using saponins as raw materials to make original NPs or as adjuvants for improving already established NPs. The physicochemical properties of saponins have been highlighted, before describing putative nano-formulations with huge promise for drug delivery and vaccine development.

It was revealed that the trimetallic cluster can detect amphetamine and morphine drugs through turn on luminescence response. The calculated binding constants are found to be <em>K</em>_a = 5.86× 10³ M⁻¹ for Amphetamine and 3.75× 10³ M⁻¹ for Morphine by using Benesi-Hildebrand equation. The trimetallic cluster also showed selective turn off luminescence response in presence of mercury (Hg²⁺) ions. The origin of the enhanced PL responses in presence of amphetamine and morphine was further investigated by exploring the PL lifetime decay studies, which reveals that larger excited state lifetime (in μs timescale) value of pristine cluster remain unchanged upon incremental addition of drugs leading to longer interaction time with the analytes. Thus, the present work undoubtedly establishes the superior drug sensing behaviour of AuAgCd-BSA tri-metallic NCs as compared to its mono-metallic and bi-metallic counterparts and open further emphasis on exploring luminescence-based sensing of narcotic drugs which has great forensic relevance.</p></div>","PeriodicalId":100959,"journal":{"name":"Next Nanotechnology","volume":"7 ","pages":"Article 100107"},"PeriodicalIF":0.0,"publicationDate":"2024-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949829524000688/pdfft?md5=bcb9957161202b16e8e683a51dabcdaa&pid=1-s2.0-S2949829524000688-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142272476","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}
