The effects of different laser structuring parameters (scanning line spacings of 40 μm, 70 μm, or 100 μm) on surface roughness were studied alongside the subsequent surface modification via stearic acid grafting. Surface topography and wettability were assessed using a contact profilometer, scanning electron microscopy, and a goniometer.

The results demonstrated that the superhydrophobic surface produced with optimised laser structuring parameter (line space 70 μm) and stearic acid modification exhibited superior corrosion resistance compared to the solely laser-structured aluminium. Additionally, these surfaces exhibited effective self-cleaning and water-repellent properties.

Arginine-terminated nanoparticles have been used as a cytosolic delivery vehicle for genes and proteins. Quantum dots (QDs), semiconductor nanocrystals with tailorable surface chemistry and bright photoluminescence ability, are utilized to deliver molecules to the cytosol and investigate the delivery mechanism of the cargo. Without a complicated polymerization process and strong oxidizers, 100 % arginine-modified quantum dots (RQDs) are prepared by the ligand exchange method and found to be colloidally stable from pH 3 to 8. This indicates that the pKa of guanidinium groups bound to the surface of RQDs is significantly lower than that of free arginine (∼12). Consequently, the QD surface has partial positive charges and hydrophobic moieties, facilitating efficient cytosolic delivery with low cytotoxicity confirmed by confocal microscopy, flow cytometry, and cross-sectional transmission electron microscopy. Inhibition drugs are used to investigate intracellular delivery mechanisms, which shows that RQDs and RQD-protein complexes are mainly taken up by an energy-independent pathway. The surface ligands were customizable to achieve a compact hydration shell and modulate the lipophilicity and charge density using the mixture of zwitterionic and R ligands. Maximal intracellular delivery of nanoparticles is achieved by the 3:1 ratio between arginine and zwitterionic ligands. The study shows that RQD-protein complexes, which include bovine serum albumin and beta-galactosidase, have been successfully co-delivered through electrostatic interactions without the need for additional genetic/post-translational modification and loss of bioactivity of protein cargos.</div></div>","PeriodicalId":22081,"journal":{"name":"Surfaces and Interfaces","volume":"61 ","pages":"Article 106096"},"PeriodicalIF":5.7,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143535409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
