The hydrothermally synthesized SBA-15 particles were surface functionalized by post-grafting synthesis method with (3-aminopropyl) triethoxy silane, mercaptopropyl trimethoxy silane and triethoxy methyl silane in order to be used as carrier materials for drug delivery. Amoxicillin was used as a model drug. The adsorption and release properties of calcined and organic-functionalized mesoporous silicas containing terminal primary amine, organothiol and methyl groups toward amoxicillin have been investigated. These mesoporous materials have been characterized using small-angle X-ray scattering (SAXS), fourier-transform infra-red spectroscopy (FT-IR), transmission electron microscopy (TEM), N-2 adsorption/desorption analysis, solid-state silicon magic-angle-spinning nuclear magnetic resonance (Si-MAS-NMR), high-performance liquid chromatography (HPLC), ultra-violet spectroscopy (UV), elemental and thermogravimetric analysis (TGA). The concentration difference and type of alkoxysilanes used for the surface functionalization have been discussed in terms of loading amoxicillin and controlling its delivery.

Surface functionalization of sba-15 particles for celecoxib delivery
Gezer, Gamze; Yılmaz, Ayşen; Department of Chemistry (2013)
Mesoporous silica particles have been used to enhance the loading capacity of drugs into these particles, increase bioavailability and control drug release. In this study SBA-15 particles were synthesized and functionalized to improve the loading capacity and release rate of drug. Then, drug loading and release process were investigated. Celecoxib was chosen as a model drug which is very hydrophobic. SBA-15 particles were used due to their highly ordered, well-defined mesoporous structure. These particles w...
Core/shell type, Ce3+ and Tb3+ doped GdBO3 system: Synthesis and Celecoxib drug delivery application
Çolak, Pelin; Ulusan, Sinem; Banerjee, Sreeparna; Yılmaz, Ayşen (Elsevier BV, 2020-12-01)
In this study, luminescent and magnetic core/shell Gd1-x-yCexTbyBO3@SiO2 nanoparticles were synthesized and used to design a drug delivery system for Celecoxib (CLX). CLX was chosen as the model drug because it is a nonsteroidal anti-inflammatory drug that is highly hydrophobic with relatively low bioavailability. The core was synthesized by Pechini sol-gel method and silica coating was carried out by a Modified Stöber method. Drug loading was carried out in ethanol with high efficiency and an improved drug...
Surface functionalization of SBA - 15 particles for amoxicillin delivery
Sevimli, Filiz F; Yılmaz, Ayşen; Department of Chemistry (2011)
There are several studies in order to control drug delivery, decrease the toxicity of drugs and also for novel biomedical applications. It is necessary to be able to control the release of the drug within the body by using drug delivery systems. Mesoporous silica compounds have only been discovered twenty years ago and they have already attracted many researchers to study these materials for several applications. SBA-15 particles have a highly ordered regular structure and are a good matrix for guest-host a...
Controlled release of vancomycin from biodegradable microcapsules
Ozalp, Y; Ozdemir, N; Kocagoz, S; Hasırcı, Vasıf Nejat (2001-01-01)
Poly D,L-lactic acid (PLA) and its copolymers with glycolide PLGA 90:10 and 70:30 were polymerized under various conditions to yield polymers in the molecular weight range 12 000-40 000 daltons, as determined by gel permeation chromatography. Vancomycin hydrochloride was the hydrophilic drug of choice for the treatment of methicillin resistant Staphyloccoccal infections. It was microencapsulated in the synthesized polymers using water-oil-water (w/o/w) double emulsion and solvent evaporation. The influence ...
Surface and modification of LP-SBA-15 with polyethyleneimine for celecoxib delivery
Farid, Ali; Yılmaz, Ayşen; Banerjee, Sreeparna; Department of Micro and Nanotechnology (2017)
In this study LP-SBA-15 (LP stands for large pores) and LP-SBA-15-PEI (PEI stands for polyethyleneimine), ordered mesoporous silica support material utilized with different pore structure characteristics to investigate on their drug delivery system abilities like release and loading properties, regarding to their structural variability and implication of surface modification. Hydrothermal synthesis method was used for synthesis of LP-SBA-15 and surface functionalization was done by polymerization of hyperbr...
