Birjandi, Afsoon Pajand; Mirnaghi, Fatemeh Sadat; Bojko, Barbara; Wąsowicz, Marcin; Pawliszyn, Janusz (American Chemical Society, 2014-11-17)Development of a straightforward strategy for simultaneous quantitative analysis of nonesterified fatty acids (NEFA) species in biofluids is a challenging task because of the extreme complexity of fatty acid distribution ... -
Biocompatible Solid-Phase Microextraction Nanoelectrospray Ionization: An Unexploited Tool in Bioanalysis
Gómez-Ríos, Germán Augusto; Reyes-Garcés, Nathaly; Bojko, Barbara; Pawliszyn, Janusz (American Chemical Society, 2015-12-09)In recent years, different geometrical configurations of solid-phase microextraction (SPME) have been directly coupled to mass spectrometry, resulting in benefits such as diminishing matrix effects, improvement of detection ... -
Cinnamaldehyde Characterization as an Antibacterial Agent toward E. coli Metabolic Profile Using 96-Blade Solid-Phase Microextraction Coupled to Liquid Chromatography–Mass Spectrometry
Mousavi, Fatemeh; Bojko, Barbara; Bessonneau, Vincent; Pawliszyn, Janusz (American Chemical Society, 2016-01-26)Sampling and sample preparation plays an important role in untargeted analysis as it influences final composition of the analyzed extract and consequently reflection of the metabolome. In the current work, mechanism of ... -
Direct coupling of solid phase microextraction with electrospray ionization mass spectrometry: A Case study for detection of ketamine in urine
Hu, Bin; Zheng, Bo; Rickert, Daniel; Gómez-Ríos, Germán Augusto; Bojko, Barbara; Pawliszyn, Janusz; Yao, Zhong-Ping (Elsevier, 2019-10-10)Electrospray ionization mass spectrometry (ESI-MS) is a commonly used technique for analysis of various samples. Solid phase microextraction (SPME) is a simple and efficient technique that combines both sampling and sample ... -
Equilibrium ex vivo calibration of homogenized tissue for in vivo SPME quantitation of doxorubicin in lung tissue
Roszkowska, Anna; Tascon, Marcos; Bojko, Barbara; Goryński, Krzysztof; dos Santos, Pedro Reck; Cypel, Marcelo; Pawliszyn, Janusz (Elsevier, 2018-06-01)The fast and sensitive determination of concentrations of anticancer drugs in specific organs can improve the efficacy of chemotherapy and minimize its adverse effects. In this paper, ex vivo solid-phase microextraction ... -
Fast Quantitation of Target Analytes in Small Volumes of Complex Samples by Matrix-Compatible Solid-Phase Microextraction Devices
Piri-Moghadam, Hamed; Ahmadi, Fardin; Reyes-Garcés, Nathaly; Boyaci, Ezel; Reyes-Garces, Nathaly; Aghakhani, Ali; Bojko, Barbara; Pawliszyn, Janusz (Wiley, 2017-06-20)Herein we report the development of solid-phase microextraction (SPME) devices designed to perform fast extraction/enrichment of target analytes present in small volumes of complex matrices (i.e. V <= 10 mu L). Micro-sampling ... -
High throughput solid phase microextraction: A new alternative for analysis of cellular lipidome?
Birjandi, Afsoon Pajand; Bojko, Barbara; Ning, Zhibin; Figeys, Daniel; Pawliszyn, Janusz (Elsevier, 2017-02-01)A new SPME method for untargeted lipidomic study of cell line cultures was proposed for the first time. In this study the feasibility to monitor changes in lipid profile after external stimuli was demonstrated and compared ... -
