Comprehensive two-dimensional liquid chromatography for the characterization of acrylate-modified hyaluronic acid
Published in Analytical and Bioanalytical Chemistry
Hyaluronic acid and its acrylate derivatives are important intermediates for various pharmaceutical, biomedical, and cosmetic applications due to their biocompatibility and viscoelasticity properties. However, these polymers are inherently difficult to characterize due to their significant heterogeneity regarding molar mass and chemical composition...
Synthesis, characterization, and application of chemically interconnected carbon nanotube monolithic sorbents by photopo...
Published in Analytical and Bioanalytical Chemistry
A facile and convenient approach for the preparation of interconnected multiwalled carbon nanotube (MWCNT) monolithic sorbents in recycled plastic caps has been developed. The method, which was based on the photopolymerization of the individual MWCNTs via the formation of a W/O medium internal phase emulsion (40/60 w/w%), provides control over the ...
Facile liquid-phase deposition synthesis of titania-coated magnetic sporopollenin for the selective capture of phosphope...
Published in Analytical and Bioanalytical Chemistry
Titania-grafted magnetic sporopollenin is synthesized by the liquid-phase deposition (LPD) technique, characterized by SEM, EDX, and nitrogen adsorption porosimetry, and used for the selective enrichment of phosphorylated peptides. The material is low cost because of easier availability of pollens and has rich surface chemistry which enables strong...

...Published in Analytical and Bioanalytical Chemistry
Quantification of ultra-trace analytes in complex biological samples using micro-solid-phase extraction followed by direct detection with internal extractive electrospray ionization mass spectrometry (μSPE–iEESI–MS) was demonstrated. 1-Hydroxypyrene (1-OHP) and papaverine at attomole levels in human raw urine samples were analyzed under negative an...
