In the present work, Na+-montmorillonite nanoclay (Na-MMT) was functionalized using 3-aminopropyltrimethoxysilane (3-APTMS) as a coupling agent. The covalent functionalization of MMT was confirmed by Fourier-transform infrared spectroscopy (FT-IR). In the specimen fabrication stage, 5 wt% of pristine MMT or silane-functionalized MMT (f-MMT) were incorporated into an epoxy system and the resulta...

Abstract Polydopamine coating is a unique, simple, and substrate‐independent surface functionalization strategy. Techniques for secondary functionalization, patterning, re‐functionalization of polydopamine modified materials are important to broaden the scope applications such in variety fields. Here, facile strategy patterning presented. This approach combines advantages three methods: coating...

Ultra-hydrophobic bilayer coatings on a glass surface were fabricated by sol-gel process using hexadecyltrimethoxysilane (C16TMS) and tetramethoxysilane (TMOS) (1:4 molar ratio) as precursors. After coating, silica nanoparticles (SiO₂ NPs) functionalized with different mono-alkoxy derivatives (methoxytrimethylsilane, TMeMS; ethoxydimethylvinylsilane, DMeVES; ethoxydimethylphenylsilane, DMePhES;...

An extract of polyphenols was obtained from organic red grape pomace, chemically analyzed, and used for functionalization two bioactive glasses porous hydroxyapatite. Functionalization is effective on hydroxyapatite the glass with higher surface reactivity a different grafting mechanism. Grafting does not inhibit redox radical scavenging activity polyphenols. The grafted make continuous layer a...

We present a new route for mass-production of B and P codoped all-inorganic colloidal Si nanocrystals (NCs) from hydrogen silsesquioxane (HSQ). Codoped Si NCs are grown in glass matrices by annealing mixture solutions of HSQ and dopant acids, and then extracted from the matrices by hydrofluoric acid etching. The free-standing NCs are dispersible in methanol without any surface functionalization...

We established a versatile method for site-specific nanopatterning of functional metallic and molecular arbitrary features in glass nanofluidic channels, with well-controlled feature sizes ranging from tens to hundreds of nanometers and precisely controlled placements in the range of several tens of nanometers. With the method, we achieved the fabrication of quasi-0D, quasi-1D, 2D, and 3D gold ...

We present a simple method for immobilizing (bio-) receptor molecules on glass surfaces using the silane 3-(triethoxysilyl)propylsuccinic anhydride (TESPSA). Its succinic anhydride functionality enables the covalent binding of amino-terminated molecules in a ring opening reaction under formation of an amide bond. We demonstrate proofof-concept using fluorescence microscopy that antibodies immob...
