ELECTROCHEMICAL SENSOR AND METHOD OF MAKING SAID SENSOR Russian patent published in 2013 - IPC G01N27/12 

FIELD: chemistry.

SUBSTANCE: invention discloses a method of making an electrochemical sensor with a detector area, electrical conductivity (σ) of which is set via tunnelling, ionisation or hopping processes, and in which electrochemical interaction with a defined substance is established; wherein the detector area is made by local application of energy, preferably by electron beam-induced deposition, wherein gaseous precursor substances present in the deposition area in immediate proximity to the substrate are energy-activated for conversion, wherein the conversion products are deposited in solid and nonvolatile form on the substrate. Also disclosed is an electrochemical sensor made using the described method.

EFFECT: enabling reliable and highly accurate detection of trace amounts or concentrations of a given chemical substance.
