Utilizing a previously validated nanoparticle-scaffolded seven enzyme cascade from glycolysis that processes glucose into 3-phosphoglycerate, we begin by confirming that non-cadmium containing ZnSe/ZnS core/shell quantum dots (QDs) made from non-toxic and earth abundant materials can replace Cd-containing QDs as a scaffolding material in the multienzyme clusters while still providing access to improved channeling activity. We then investigate the role of enzyme assembly order within mixed NP systems that consist of both spherical QDs and rectangular 2-dimensional nanoplatelets (NPLs). Along with physicochemical confirmation of enzyme assembly to the QDs and enzyme-induced cluster formation, the rate of overall catalytic flux for each of the systems was monitored under different assembly conditions. The results reveal that adjusting relative NP concentration normalized to surface area, enzyme assembly order, and choice of initial material in any mixed NP clustered configuration are critical to attaining further improvements in catalytic flux via channeling. The potential ramifications of these observations in the context of assembling designer biosynthetic cascades that use bulk feedstock materials derived from agriculture to create new and useful products are then discussed.</p><h3>Graphical Abstract</h3><p>Schematic of a self-assembled mixed QD-NPL-enzyme system engaged in 7-enzyme sequential substrate channeling.</p>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"27 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11051-025-06265-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143628718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper develops an integrated energy-based theoretical framework that predicts how melting entropy and specific heat change based on sized-dependent characteristics in metal nanoparticles with copper (Cu), aluminum (Al), and indium (In). The model shows a clear association between nanoparticle size reduction and cohesive energy decrease which results in measurable patterns of melting temperature reduction and entropy and heat capacity modifications. Nanoparticle size reduction leads to decreased melting entropy because of surface energy effects and simultaneously results in higher specific heat values because atomic vibrations become more prominent.

However, applying this encapsulation method, initially developed for CdSe-based QDs, to InP-based QDs results in a significant decrease in photoluminescence quantum yield (PLQY). To understand this discrepancy, we prepared three types of QDs (InP/(ZnSe)<sub>n</sub>/ZnS, with <i>n</i> = 4, 6, 8 monolayers) that emit in the green region and encapsulated them into silica particles (~ 30 nm in size, typically containing ~ 10 QDs per particle). Increasing the thickness of the intermediate ZnSe layer from 1.3 (4 monolayers) to 2.7 nm (8 monolayers) using the same core size (1.6 nm) effectively suppressed the decrease in PLQY after encapsulation. Quantum mechanical calculation revealed that compared to CdSe-based QDs, the excited electron in InP-based QDs tends to spread significantly due to the lighter effective electron mass and lower barrier height from the InP core to the ZnSe and ZnS shells. As the ZnSe layer thickness increases, the amount of spread electron reduces, thereby better maintaining the PLQY after encapsulation. The calculations further suggest that larger cores (> 2.2 nm) and thicker shells (> 2.5 nm) are preferable for achieving high PLQY after silica encapsulation. This knowledge serves as a guideline for developing ideal QDs with bright, robust, and non-toxic features as user-friendly phosphors.</p></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"27 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
