The influence of MCC integrated on the contact angle, porosity, water flux, and BrO3− adsorption performance was also examined. The addition of MCC, up to 5 wt%, resulted in a significant decline in the contact angle from 60.1° of neat PES to 43.1°, indicating an increase in membrane hydrophilicity. Moreover, MCC incorporation at 1, 3, and 5 wt% concentrations led to an enhancement in the water flux to 169, 178, and 180 L m−2 h−1, respectively, indicating the improved membrane permeability. MCC-integrated PES membranes exhibited enhanced antifouling properties, as demonstrated by the achieved high flux recovery ratio (99%) of the 5% MCC-containing membrane. Furthermore, all MCC-integrated PES membranes exhibited superior performance in the removal of bromate ions (BrO3−), with rejection rates of 60.8%, 80.2%, and 92% for 1%, 3%, and 5% MCC, respectively, which was much greater than that of the virgin PES membrane.</div>","PeriodicalId":10483,"journal":{"name":"Colloid and Interface Science Communications","volume":null,"pages":null},"PeriodicalIF":4.5,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49715067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we quantified the cellular adsorption and internalization kinetics and correlated them with the subcellular distribution of AuNRs. It is found that the distribution ratio between internalized and surface-adsorbed AuNRs decreases with increasing AR, with modest AR of 3.2 being most favorable for long-efficient delivery into cells. Long edge and blunt tip, critical to the adsorption and internalization, are simultaneously satisfied by this modest AR. Other ARs cause obvious barriers in the intermediate steps, contributing to uneven subcellular AuNR accumulation. Additionally, internalization shifts from spontaneous wrapping to clathrin-mediated ATP-dependent endocytosis with increasing AR. Inhibition of the endocytic pathways can reduce the distribution ratio, with the magnitude of effect depending on their importance to the internalization.

Natural antimicrobial agents can promote bone production while sterilizing. In this paper, Polypyrrole (PPy) is driven in situ by pulsed electrochemical deposition. Under the oxidation potential, the amino group of Pyrrole (Py) monomer interacts with PO43− and Dexamethasone root ion(Dex−) in the electrolyte through electrostatic interaction. The phenolic hydroxyl group chitosan quaternary ammonium salt (2-hydroxypropyltrimethyl ammonium chloride chitosan, HTCC) interacts with N atom of the amino group on Py and forms hydrogen bonds to assist Py in regulating Dexamethasone (Dex) the drug. While under the reduction potential, OH− is produced near the working electrode to promote the generation of HA, and finally forms the PPy@HA/Dex/HTCC composite coating. The study show that the composite coating is spherical nanoparticles with uniform distribution, and the regulation effect of PPy reduces the release rate of Ca2+ and Dex− from the coating, making it release smoothly and slowly.
