Four proteins were found to bind to CdS and cap the growth of CdS quantum dots, leading to precise size control, as evidenced by absorbance and fluorescence spectra. Increasing the concentration of CdS does not change the absorbance and emission peaks, thereby indicating that the proteins effectively constrain the size of the quantum dots. Employing different proteins also yielded quantum dots with distinct optical and physical properties, including the appearance of biomediated nanorods when SynI3 was utilized. Moreover, the <i>de novo</i> proteins effectively maintained the stability of the quantum dots for up to 7 days, surpassing the stability of quantum dots capped by the small molecule, l-cysteine.

This study reports on a two-dimensional (2D) binary superlattice of individually exfoliated BNNTs with a negative surface charge (p-BNNT25) and cationic surfactant vesicles (CTAT/SDBS vesicles, prepared by mixing cetyltrimethylammonium tosylate (CTAT) and sodium dodecylbenzenesulfonate (SDBS)) complexes through electrostatic interactions. Depending on the surface charge density of the CTAT/SDBS vesicles and the mass ratio between the CTAT/SDBS vesicle and p-BNNT25, the CTAT/SDBS-BNNT complexes formed highly ordered superstructures. These structures include an intercalated lamellar phase with a centered rectangular structure (ICLP), in which a 2D array of p-BNNT25 is inserted into the multilamellar structure, and an AB<sub>3</sub> structure, in which the BNNTs are surrounded by surfactant micelles in a triangular arrangement. To the best of our knowledge, this is the first demonstration of the fabrication of highly ordered superstructures of individually exfoliated and negatively charged BNNTs with positively charged surfactant vesicles through electrostatic interactions. This approach for the 2D binary superlattices of CTAT/SDBS-BNNT complexes induced by electrostatic interactions is expected to be beneficial for a wide range of one-dimensional (1D) nanoparticle applications.</p>","PeriodicalId":10,"journal":{"name":"ACS Central Science","volume":"11 6","pages":"950-959"},"PeriodicalIF":12.7,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12203259/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144525300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
