Abstract
The influence of modification of MF-4SC membranes with silica (or surface-hydrophobized silica) nanoparticles on their ionic conductivity and diffusion permeability as well as the response stability and sensitivity of the membrane-based DP-sensors for cations of amino acids containing hydrophobic fragment has been studied. The membranes modified with surface-hydrophobized silica exhibited the 2–5 times reduced relative error of determination of the hydrophobic amino acids as compared to the initial membranes.
