The reducing groups inherent in bovine serum albumin (BSA) facilitate a redox reaction with potassium permanganate (KMnO4), while the abundance of functional groups in BSA is instrumental in the formation of MnO2. The transmission electron microscopy (TEM) analysis has characterized the synthesized MnO2 nanoparticles, termed BM NPs, as spherical particles with a mean diameter of 210 nm and zeta potential of −40.1 mV measured by dynamic light scattering (DLS). The Fourier transform infrared (FT-IR) spectrum of BM NPs exhibits the characteristic peak of MnO2 at 1113 cm−1 and 620 cm−1. Furthermore, the elemental composition of BM NPs has been ascertained through energy-dispersive X-ray (EDX) elemental mapping analysis. Though concentration of BM NPs up to 200 μg/mL, the survival rate of 4T1 cells remained approximately 75 %. Given that BM NPs at a concentration of 100 μg/mL significantly alleviate cellular hypoxia, the high oxygen-generating capacity of these nanoparticles is proved, suggesting their suitability as a drug delivery system, especially in the context of hypoxic tumor microenvironments.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"10 12","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142210740","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}

For detecting PNP, a colorimetric method utilizing a nanozyme that mimics laccase activity presents a viable approach. In this study, PV14@MIL-88A, a robust nanozyme with superior laccase-mimic capabilities, was synthesized by incorporating Na7H2[PV14O42] (PV14) into MIL-88A, a metal-organic framework (MOF). This nanozyme demonstrates optimal laccase-mimicking activity, enabling effective PNP detection via colorimetry and digital image colorimetry using smartphones. Theoretical analyses suggest that the outstanding laccase-mimic activity of PV14@MIL-88A is derived from the optimized d-band center in PV14. Upon calcination with dicyandiamide (DCDA), PV14@MIL-88A transforms into Fe2O3/VO2@NCNF. In the presence of NaBH4, Fe2O3/VO2@NCNF facilitates the conversion of PNP to p-aminophenol (PAP), an essential precursor in paracetamol synthesis. The interaction between Fe2O3 and VO2 in Fe2O3/VO2@NCNF enhances adsorption and subsequent reduction of PNP. The saturation magnetization of Fe2O3/VO2@NCNF reaches 25 emu g−1, which supports efficient magnetic separation in the reduction process. This study not only advances an effective method for PNP detection but also facilitates its transformation from a hazardous pollutant into a valuable chemical precursor.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142210752","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}

Thus, this work developed the nano-in-microparticles containing RIF (trojan nRIF) as a novel pulmonary delivery system. The RIF-loaded nanoparticles (nRIF) were prepared by self-assembly polyelectrolyte complexation between lecithin and chitosan, whereas the trojan nRIF were formulated by spray-drying method of nRIF and mannitol/maltodextrin. The nRIF had a spherical shape with sizes of 86–126 nm, zeta potentials of 24–39 mV, entrapment efficiencies of 44–80 %, and drug loading capacities of 13–42 %. The RIF release from nRIF occurred in two stages, the initially rapid release stage and the controlled release stage upto 96 h, followed the Higuchi model. The trojan nRIF possessed the mass median aerodynamic diameter of 3.7–4.6 μm, fine particle fraction of 34–40 %, and alveolar fraction of 17–21 %. Compared to mannitol, maltodextrin was a superior carrier for nRIF, which yielded better aerodynamic properties and RIF was mainly stayed in the amorphous form. Moreover, using the scanning electron microscopy, the nano-in-microparticles were clearly observed with hollow structure. Finally, the trojan nRIF could preserve the physical properties of the encapsulated nRIF. In summary, the trojan nRIF could become a potential inhalation anti-tuberculosis product.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"10 12","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142210755","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}

The procedure from aggregation to disaggregation usually causes a revival of emission signals, and thus affords an interesting new path to design “turn-on” optical probes. For this purpose, the photophysics, energetics and dynamics of supra-molecular encapsulation induced disaggregation of a self-assembled bis-indole derivative, 3,3’-bisindolyl(phenyl)methane (BIPM), and its further reaggregation are reported herein. Compared to disaggregation strategies, its reverse process, reaggregation, has received much less attention so far. The gamma-cyclodextrin (γ-CD) molecules were found to be effective in disaggregating the BIPM associations and emission enhancement, whereas, the incorporation of guanidine hydrochloride (Gnd-HCl) into the aqueous solution of disaggregated BIPM monomers in γ-CD environment resulted in probe reaggregation leading to quenching of the restored emission. Here, γ-CD and Gnd-HCl can be considered as the molecular modulators of BIPM fluorescence based on the disaggregation–reaggregation mechanisms. The spectroscopic and thermodynamic findings associated with the disaggregation-reaggregation processes might be insightful in reversible controlling of molecular aggregation and the associated optical properties for diverse applications.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142210754","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}

The heterojunctions and Au nanoparticle decoration induce the electron-rich interfaces in the catalyst, which facilitate the synergistic adsorption of both OER and HER intermediates. As a result, MoS2/Ni3S2-Au@NF possesses an excellent bifunctional electrocatalytic performance in 1 M KOH with low HER overpotential (78 mV@10 mA cm−2, 253 mV@500 mA cm−2), low OER overpotential (261 mV@50 mA cm−2, 435 mV@500 mA cm−2), and outstanding cyclical stability and continuous stability, which are superior than typical benchmarks of Pt/C and RuO2. An electrolyzer assembled with the self-supported MoS2/Ni3S2-Au@NF electrode also displays excellent OWS activity and stability with a current density beyond 100 mA cm−2.

Here, Ni doping facilitated the tuning of electronic properties, leading to a significant increase in the rectification ratio from 238 to 1172, along with a reduction in the potential barrier height from 0.67 V to 0.65 V. This is attributed to Ni's role as a charge carrier in ZFO, enhancing carrier concentration, confirmed by Mott-Schottky analysis. The 5 mol % Ni-doped ZFO also exhibited remarkable light sensitivity, with its rectification ratio surging to 1795 under illumination, four times that of the undoped version. Additionally, its photo-sensitivity soared to 42.46 %, nearly quadrupling the undoped device's performance, and its power gain impressively climbed to 38.4 %, which is over twelvefold the undoped sample's output. Furthermore, the diode responds strongly to optical illumination, making this structure suitable for use as a photodiode or photosensor. Apart from that by employing a doping strategy, we achieved 64.61 % degradation of methylene blue dye under visible light in 120 minutes, compared to 36.85 % for the undoped sample.
