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":null,"pages":null},"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":null,"pages":null},"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.

In order to improve response selectivity, Ti-MOF/TiO2 film was modified with 1,3,3-trimethylindolinonaphthospirooxazine (SP) forming SP@Ti-MOF/TiO2 COWG. This modified COWG showed improved selectivity response by showing robust response to EDA and a negligible response to others. When the EDA gas molecule was adsorbed on the surface of the membrane, charge transfer between them preferentially occurred, leading to a change in the optical parameter.

A consensus has been reached that the droplet depinning force mainly stems from the synergistic dynamics of the three-phase contact line and the liquid-vapor interface. Nevertheless, the above conclusions were made using simple (pure water) droplets depinning on rigid superhydrophobic surfaces, denoted as simple rigid wetting, where the main influencing factors are liquid-vapor interfacial tension, surface texture geometry, and material wettability. In recent years, an increasing amount of attention has been paid to complex soft wetting, where liquid physiochemical properties (e.g., viscoelasticity) and solid surface rigidity play an important role. To encourage the investigation of complex soft wetting, in this perspective, depinning of simple droplet on soft surfaces and depinning of viscoelastic droplets on rigid surfaces will be briefly introduced. Then, possible factors that affect viscoelastic droplet depinning on soft superhydrophobic surfaces will be discussed. Moreover, applications that are highly relevant to complex soft wetting will be introduced.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48786240","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}

This research focuses on extracting natural dyes from Butea Monosperma plants and on developing sustainable dyeing methods for silk fabric. Natural colorants were extracted using an aqueous and acidic extraction procedure, and the silk fabric was dyed with the extracts using mordanting with a variety of metal and bio mordants. The treatment of fabric and extracts were carried out using microwave irradiation. It was found that after irradiation up to 3 min, the acidic extract shown maximum color strength onto fabric. It was also observed that the acacia and pine-nut hull at 80 °C and before dyeing pomegranate extract at 80 °C and after dyeing of silk fabric at 40 °C using bio-mordants were higher color strength than metallic mordant. For comparative analysis Al salt at 40 °C, Iron salt at 60 °C and tannic acid (T.A.) at 80 °C were provided acceptable results. The color fastness characteristics were also found good to excellent. The bio-mordants not only provide the higher color strength and fastness properties, it was also an environmental friendly approaches. Scanning electron microscopy (SEM) images and Fourier transform infrared spectroscopy (FT-IR) analyses revealed the difference between irradiated and un-irradiated silk fabric. Therefore, it is recommended that MW rays and bio-mordants be used in the natural dyeing of silk fabric because of their deformability and non-toxicity, as well as their high color fastness and color strength properties.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47563544","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}
