The focus of this study is development of a new, convenient, rapid and sensitive electromembrane extraction approach (based on an ionic liquid-supported MWCNTs/ZnO reinforced hollow fiber, for the first time) as an off-line sample clean-upipreconcentration method coupled with capillary electrophoresis (CE-UV) using field-amplified sample injection (FASI) for quantification of Imatinib mesylate in human plasma. The nano-hybrid sorbent, coated by 1-octyl-3-methylimidazolium bromide ionic liquid (E0M1m]Br) in this research, was prepared by a feasible basic catalyzed sol-gel method. Then, it was immobilized (supported by capillary forces and sonication) in pores of a segment of a polypropylene hollow fiber membrane as the extraction unit after dispersing in 2-nitrophenyl octyl ether (NPOE) solvent and subsequently served as the supported liquid membrane (SLM) composition. Significant variables affecting the proposed method were evaluated and optimized to achieve the maximum extraction performance. Optimal conditions were obtained by NPOE with 4 mg mL(-1) nano-sorbent as the SLM composition, 105 V as the driving force, pH 2 and 1.8 of the donor and acceptor phases, respectively, an extraction time of 15 min and an agitation rate of 800 rpm. The developed method was validated according to FDA guidelines. Regarding the validation results, the method is proved to be linear (R-2 = 0.998) over concentrations ranging from 25 to 1500 ng mL(-1) (LOD = 6.24 ng mL(-1)). The mean RSD values for intra- and inter-day precision studies were 6.83 and 7.71%, respectively and the mean recoveries ranged between 98 and 106%. Finally, the validated method was successfully applied for sensitive, selective and rapid determination of Imatinib in patient's plasma samples. (C) 2017 Elsevier B.V. All rights reserved.

Usage of microwave and ultrasound in the extraction of essential oils and phenolic compounds İnce, Alev Emine; Şahin, Serpil; Şümnü, Servet Gülüm; Department of Food Engineering (2011) The objective of this study is to extract phenolic compounds from nettle and melissa by using microwave and ultrasound and to compare these methods with conventional extraction and maceration, respectively. Extraction of melissa essential oil was also studied. In extraction of phenolics, effects of extraction time (5-20 min for microwave; 5-30 min for ultrasound) and solid to solvent ratio (1:10, 1:20, 1:30 g/ml) on total phenolic content (TPC) were investigated for microwave and ultrasound extractions.

Surface functionalization of SBA-15 particles for amoxicillin delivery Sevimli, Filiz; Yılmaz, Ayşen (2012-08-01) 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. ...
Direct insertion probe mass spectrometry of polymers Hacaloğlu, Jale (2012-04-16) This chapter reviews advances in the technique of direct insertion probe mass spectrometry (DIP-MS) and its applications in polymer analysis for various purposes. The applications for thermal characterization involve investigation of the thermal stability, degradation products, and decomposition mechanism of complex polymer samples, in particular polymers involving flame retardants, polyphenylene- and poly(phenylene vinylene)-based materials, and coalesced homopolymers and polymer blends. Examples focused o...
Thermal degradation processes of poly(carbonate) and poly(methyl methacrylate) in blends coalesced either from their common inclusion compound formed with γ-cyclodextrin or precipitated from their common solution Uyar, Tamer; Oguz, Gulcan; Tonelli, Alan E.; Hacaloğlu, Jale (2006-10-01) Direct insertion probe pyrolysis mass spectrometry (DIP-MS) analyses of a PC/PMMA blend, coalesced from their common inclusion compound (ICs) formed with host gamma-cyclodextrin (gamma-CD) through removal of the gamma-CD host, and a physical PC/PMMA blend, precipitated from their common solution, have been performed and compared with those of the coalesced and as-received homopolymers. A slight increase in the thermal stability of the PMMA component in the presence of PC was recorded both by TGA and DIP-MS ...
Live-cell imaging of Pol II promoter activity to monitor gene expression with RNA IMAGEtag reporters SHIN, Ilchung; RAY, Judhajeet; Gupta, Vinayak; İlgü, Müslüm; Beasley, Jonathan; BENDICKSON, Lee; MEHANOVIC, Samir; Kraus, George A.; Nilsen-Hamilton, Marit (Oxford University Press (OUP), 2014-01-01) We describe a ribonucleic acid (RNA) reporter system for live-cell imaging of gene expression to detect changes in polymerase II activity on individual promoters in individual cells. The reporters use strings of RNA aptamers that constitute IMAGEtags (Intracellular MultiAptamer GEnetic tags) that can be expressed from a promoter of choice. For imaging, the cells are incubated with their ligands that are separately conjugated with one of the FRET pair, Cy3 and Cy5. The IMAGEtags were expressed in yeast from ...
