Gold electrodes were chemically modified with thioctic acid monolayer designed to mimic biological ion-channel membranes. The technique was then used in the determination of alkali, alkaline earth, thallium(I), and lanthanum metal cations as analytes

The ion-channel sensor technique was used to determine heparin concentrations in artificial and horse serum with cyclic voltammetry. The sensor is based on self-assembled monolayers (SAMs) of thioctic acid on which protamine is attached as a receptor

The detection of protamine, a polycation, by use of electrodes modified with self-assembled monolayers of thioctic acid is reported. These sensors can detect protamine concentrations as low as 0.5 μg/mL when [Ru(NH3)6]3+ is used as marker and 2.0 μ

A simultaneous flow-injection analysis (FIA) manifold that could analyse three ions from a single injection was designed, constructed, calibrated and used successfully to analyse Li(+), Na(+) and K(+). This FIA method was 10 times faster than the bat
