in this work we synthesized nano hydroxyapatite (hap)  by sol-gel method, then we functionalized hydroxyapatite nanoparticle by use of  3-aminopropyl trimethoxysilane (aptms) , to improve the loading and control release of sulfasalazine drug bonded to aptms. the drug release patterns from sulfasalazine loaded hap nanoparticles at ph value 8 for 6h, sulfasalazine loaded functionalized hap nanopa...

Considerable studies have been performed on the development of optical fiber sensors modified by gold nanoparticles based on the localized surface plasmon resonance (LSPR) technique. The current paper presents a new approach in fiber surface modification technology for biosensors. Star-shaped gold nanoparticles obtained through the seed-mediated solution growth method were found to self-assembl...

We used a simple electrospinning technique to fabricate a highly potent silver-organoalkoxysilane antimicrobial composite from AgNO3-polyvinylpyrrolidone (PVP)/3-aminopropyltrimethoxysilane (APTMS)/tetraethoxysilane (TEOS) solution. Spectroscopic and microscopic analyses of the composite showed that the fibers contain an organoalkoxysilane 'skeleton,' 0.18 molecules/nm2 surface amino groups, an...

We demonstrate reduced surface recombination velocity (SRV) and enhanced power-conversion efficiency (PCE) in mixed-cation mixed-halide perovskite solar cells by using (3-aminopropyl)trimethoxysilane (APTMS) as a passivator. show the APTMS serves to passivate defects at surface, while also decoupling from detrimental interactions C60 interface. measure SRV of ?125 ± 14 cm/s, concomitant increas...

Optimization of performance of holographic gratings was investigated by changing the chemical structures of photopolymerizable monomers, the LC content, and recording beam intensity, which strongly related to the control of kinetics of polymerization and phase separation of LCs. High diffraction efficiency was obtained using 3-acryloxypropyltrimethoxysilane (APTMS) and 2-[(3,4-epoxycyclohexyl)e...

In this study, functionalization of PET fabrics with amino groups was achieved by aminolysis. Aminolysis routes were explored using different amine-based materials including ethylenediamine (EDA), triaminotriethylamine (TAEA) and (3-aminopropyl)trimethoxysilane (APTMS), (3-trimethoxy-silylpropyl)diethylentriamine (TRIAMO) in addition to amino-functionalized silica nanoparticles as amino-silane ...

This paper describes the fabrication of a novel microbore monolithic column modified with magnetite nanoparticles (MNPs) prepared in poly(ethylene-co-tetrafluoroethylene) (EFTE) tubing, and its application as stationary phase for chromatographic separation phosphorylated compounds. In order to obtain composite column, two-step procedure was performed. The formation glycidyl methacrylate-based m...

Carbon nanostructures-silica aerogel composites were synthesized and characterized to assess the effect of carbon nanotubes (CNTs) or graphene oxide (GO) on silica properties. The sol-gel chemistry was based methyltrimethoxysilane (MTMS) 3-aminopropyltrimethoxysilane (APTMS) as precursor system, with varying amounts APTMS (0–20% mol Si). significantly impacted materials' physical microstructure...
