Abstract
This article briefly outlines the history of a multi-year study based on a physical-technical approach to electrochemical sensors and primary information converters (transductors). The main goal of the study is to increase the volume of objective information in the electroanalytical signal. It is shown that this can be achieved by increasing the number of degrees of freedom of the signal from one to three. Such a 3D analytical signal is a digital, exclusive electrochemical pattern of the sample.
Electrochemical interactions are the essence of living matter. It is shown that even a simple three-electrode electrochemical cell can yield a very large volume of information in the form of a digital, exclusive electrochemical pattern.
The developed prototypes of operational devices, their key parameters, and methods that can be effectively used with the Lab-on-Layered-System, a technological 3D platform for portable complete analytical systems with a disposable cartridge, are presented. The combination of a 3D digital analytical signal and innovative 3D sensor technology can yield promising results for the creation of portable and remote point-of-care devices.
