Running Title: Chiral analysis of microalgae amino acids by MEKC-LIF ABSTRACT In this work, a chiral and a non-chiral micellar electrokinetic chromatography with laser-induced fluorescence detection (MEKC-LIF) have been combined to identify and quantify a group of D-and L-amino acids (D/L-aa) in different microalgae samples. The combination of the non-chiral and chiral-MEKC-LIF methods made eas...

Gold nanoparticles prepared by chemical reduction in sodium dodecyl sulfate (SDS) solution are size-controlled with the addition of pyrene. Micellar electrokinetic capillary chromatography (MEKC) is applied to the system to examine the size and polydispersity of gold nanoparticles and to show that pyrene has the extraordinary effect in decreasing the size and narrowing the dispersity of gold na...

human interferons (ifns) are key cytokines secreted by immune system. they have several effects such as antiviral and anti tumors activity, activating immune cells and healing of multiple sclerosis. the type ifns present in humans are α, β and υ. ifn β is a polypeptide, normally produced by fibroblasts and seems to be more species-specific than ifn . structural properties of i fns are importan...

Micellar electrokinetic chromatography (MEKC), one of the major capillary electrophoresis (CE) modes, has been interfaced to mass spectrometry (MS) to provide high sensitivity and selectivity for analysis of chiral compounds. The research in this dissertation presents the development of novel polymeric glucopyranoside based molecular micelles (MoMs) (aka. polymeric surfactants) and their applic...

Abstract This work presents an innovative silica-layer coated capillary with comparison study of the and fused-silica for separation seven phenolic acids viz . p -hydroxyphenylacetic acid (PHPA), -coumaric (PCA), -hydroxybenzoic (PHBA), caffeic (CFA), (3,4-dihydroxyphenyl)acetic (DHPA), gallic (GLA), 2,3,4-trihydroxybenzoic (THBA), together caffeine (CF), by electro-chromatography (CEC) micella...

A cyclodextrin-modified micellar electrokinetic chromatography (CD-MEKC) technique has been developed for enantioseparation of vinpocetine using an inexpensive 2-hydroxypropyl-β-CD (HP-β-CD) as the chiral selector (CS). The best chiral separation was achieved using 40 mM HP-β-CD as the CS in 50 mM phosphate buffer (pH 7.0) consisting of 40 mM sodium dodecyl sulfate (SDS) at a separation tempera...

In this study, micelles prepared from distearoylphosphatidylethanolamine with covalently attached poly(ethylene) glycol) (PEG) of molecular weight 2000 (DSPE-PEG-2000) were employed in micellar electrokinetic chromatography (MEKC) as pseudostationary phases. Since DSPE-PEG-2000 contains long hydrophobic alkyl chains, an anionic phosphate group, and hydrophilic PEG chains, the prepared micelles ...

A micellar electrokinetic chromatography (MEKC) method was applied for the identification of geographical origins of Chinese green teas. Under the optimized conditions, chromatographic profiling of collected Maojian tea samples was obtained. Based on MEKC-UV profiling, twenty-four tea samples were successfully differentiated according to the relative peak areas of selected peaks in the chromato...
