We introduce a novel preconcentrating technique by using surface modification of palladium nanoparticles (Pd-NPs) with octadecane thiol (ODT) prepared in toluene for selective and sensitive extraction of proteins (insulin, ubiquitin, lysozyme) from a variety of real-world samples including pancreas, mushroom

The generation of retention index (RI) libraries is an expensive and time-consuming effort. Procedures for the transfer of RI properties between chromatography variants are, therefore, highly relevant for a shared use. The precision of RI determination and accuracy of RI

Understanding bacterial adhesion on a surface is a crucial step to design new materials with improved properties or to control biofilm formation and eradication. Sum Frequency Generation (SFG) vibrational spectroscopy has been employed to study in situ the conformational response

In this study, the open-tubular electrochromatographic (OT-CEC) migration behavior of various peptides has been characterized using etched and chemically (n-octadecyl- and cholesterol-) modified capillaries, interfaced to an electrospray ionization mass spectrometer through a sheath liquid configuration. The stationary phases were
