Chemical surface modification methods were investigated to activate surface of poly-(dimethylsiloxane) (PDMS) for probe immobilization in enzyme-linked immunosorbent assay (ELISA). The investigations started from dramatization of PDMS surface with (3-aminopropyl)-triethoxysilane (APTES). Amino groups generated by APTES were either derived into carboxyl group by Succinic acid anhydride (SAA), th...

Abstract The increasing emission of carbon dioxide (CO 2 ) to the atmosphere has gained worldwide concern due its main contribution climate changes, global warming, and greenhouse effect. Numbers technologies have been carried out remove this hazardous gas from environment such as absorption, adsorption, membrane separation, cryogenic biological process. Due limitation current absorption techni...

The field of optical thin films has garnered significant attention due to their potential applications in visible light communication, sensing, and imaging. Among the various fabrication methods available, conventional layer-by-layer (LBL) dip coating is less sophisticated more economical. Nevertheless, this approach frequently encounters deficiencies precise control growth films. This work aim...

This work attempted to fabricate superhydrophobic fabric via a simple immersion technique. Textile fabrics were coated with silica nanoparticles prepared from tetraethoxysilane (TEOS) obtain sufficient roughness hydrophobic surface chemistry. Then, the treated polydimethylsiloxane (PDMS) and aminopropyltriethoxysilane (APTES) reduce energy. The effects of PDMS concentration on morphology superh...

Antibody immobilization strategies (random, covalent, orientated and combinations of each) were examined to determine their performance in a surface plasmon resonance-based immunoassay using human fetuin A (HFA) as the model antigen system. The random antibody immobilization strategy selected was based on passive adsorption of anti-HFA antibody on 3-aminopropyltriethoxysilane (APTES)-functional...

Well-defined, stable and highly structured I2 (Fd3̅m) liquid crystalline nanoparticles (LCNP) of 50/50 (wt/wt) soy phosphatidylcholine (SPC)/glycerol dioleate (GDO), can be formed by using a low fraction (5-10 wt%) of the dispersing polymeric surfactant polyoxyethylene (20) sorbitan monooleate (polysorbate 80 or P80). In the present study we used small angle neutron scattering (SANS) and deutera...

A luminescent inorganic-organic hybrid material was synthesized by covalent immobilization of a europium bipyridine carboxylate complex on the inner pore walls of the mesoporous silica host MCM-41 using the grafting method. Guest-host binding was achieved through double functionalization of the host surface with organosilane reagents (trimethylsilyl, TMS, and aminopropyltriethoxysilane, APTES) ...

The CO2 adsorption capacity of different functionalized mesoporous silicas of the SBA-15 type was investigated and the influence of textural properties and the effect of the silicon source on the CO2 uptake studied. Several adsorbents based on SBA-15 were synthesized using sodium silicate as silicon source, replacing the commonly used tetraethyl orthosilicate (TEOS). Thus, we synthesized three ...

Background: Silane-containing universal adhesives (UAs) are marketed as adhesion promotors for glass-ceramics. Objectives: This study aimed to evaluate the priming capacity of γ-methacryloxypropyltrimethoxysilane (γMPTS)-containing and γ-methacryloxypropyltriethoxysilane (γMPTES)/3-(aminopropyl)triethoxysilane (APTES)-containing lithium disilicate ceramic (LDC). Materials Methods: Etched LDC di...
