Due to their extremely low thickness (∼10 nm), this oxide layer is easy to destroy under corrosion conditions. Through plasma electrolytic oxidation (PEO), titanium and titanium alloys can be equipped with thick and adhesive TiO2 coatings to enhance their surface characteristics. In the PEO process, TiO2 composite coatings can be formed by mixing proper additives with electrolytes, such as powders, particles, sheets, or compounds. The graphene and its family derivatives (i.e., graphene oxide and reduced graphene oxide) are among the most popular additives used in PEO composite coatings due to their high stability in corrosive media. Graphene family nanosheets can accumulate in PEO coatings because of their porous nature, changing the surface characteristics dramatically. The use of graphene family nanosheets in the electrolyte can be useful to reduce coating porosity and improve final corrosion properties by adjusting electrolyte conditions. Therefore, the diffusion pathways for corrosive ions in composite TiO2 coatings become considerably more tortuous than with pure TiO2.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48295881","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}

It is significant to understand and control the interactions among biomaterials and proteins for several biomedical applications. Surface engineering plays a significant role to determine biocompatibility via tuning the effects directly on proteins. In this study, amino acid (histidine and leucine) conjugated self-assembled molecules (SAMs) were synthesized and used to modify silicon dioxide (SiO2) surfaces to investigate protein adsorption behavior. SiO2 surfaces were modified with (3-aminopropyl) triethoxysilane (APTES) conjugated histidine and leucine amino acids. Modified SiO2 surfaces were characterized by water contact angle measurements (WCA) and X-Ray Photoelectron Spectroscopy (XPS) analysis. Protein adsorption [Human Serum Albumin (HSA), fibrinogen, and Immunoglobulin G (IgG)] on SiO2 coated crystals was investigated in situ by using Quartz Crystal Microbalance (QCM) biosensor. According to the results, model proteins have shown different selectivity to the amino acid conjugated SiO2 coated crystals depending on the type of the amino acids and concentration. Consequently, this controlled chemistry on the surface of biomaterials has a great potential to manipulate protein adsorption and enhance the biocompatibility of biomaterials for various biomedical applications.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42239126","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}

We discussed systematically the influence of synthesis conditions on the structure and size of MNPs in co-precipitation method without stabilizer in one system. NH4OH/Fe3+ ratio, Fe3+/Fe2+ ratio, initial concentration of HCl, total concentration of iron ions, reaction temperature, aging time and washing times were investigated. The surface of magnetite crystal was easily oxidized at high NH4OH/Fe3+ ratio, and the high pH value of the reaction system can induce the large crystalline size. The hydrodynamic diameter of MNPs was efficiently controlled by the equilibrium of DLVO forces and non-DLVO forces. An appropriate initial concentration of HCl and higher reaction temperature can reduce the crystalline size due to the decelerated nucleation rate. The aging time and the total concentration of iron affected the crystalline size positively. Noticeably, pH value of MNPs dispersion in distilled water would remarkably reduce after each washing by centrifugation due to surface absorption of hydroxy group. This research provided the fundamental support for the reproducible preparation of MNPs in co-precipitation method.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47454465","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}

Agarose gels with concentrations of 0.5%, 1.0%, and 1.5% w/v were selected for the degradation study to show that the mechanical effects of degradation could be measured in a spatially resolved way on hydrogel surface. Agarase enzyme was used to degrade the agarose gels. The agarose gels were found to be heterogeneous with multiple stiffness domains that were degraded with different erosion rates. It was inferred that agarose gels contained both tightly and loosely packed regions. The loosely packed regions degraded first, followed by the regions that were packed more tightly. Second hydrogel containing hyaluronic acid and gelatin with 5% w/v hyaluronic acid and 5% w/v gelatin cross-linked in equal amounts were also studied. These hybrid gels were degraded either by using hyaluronidase or collagenase type IV. With hyaluronidase, gelatin was left on the surface as a homogenous layer. With collagenase, cross-linked hyaluronic acid remained on the surface. Post-degradation the hyaluronic acid rich surface had a stiffness of ∼20 kPa, while the gelatin rich surface stiffness was only ∼15 kPa.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2022-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43463978","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}
