Electrochemical biosensor for direct registration of myoglobin based on carbon nanotubes and a molecularly imprinted polymer based on o-phenylenediamine and a method for its preparation

摘要

1. Electrochemical biosensor for direct registration of myoglobin in aqueous buffer solutions by measuring the height of the peak of electroreduction of myoglobin by square-wave voltammetry, which is a planar electrode modified with carbon nanotubes and an analogue of antibodies to myoglobin, which is an o-phenylene polymer molecularly imprinted for myoglobin.2 . The method of producing an electrochemical biosensor for direct registration of myoglobin according to claim 1, which means that the surface of a planar electrode is modified with a suspension of carbon nanotubes obtained by ultrasonic disintegration of carbon nanotubes in an organic solvent, followed by modification of the obtained electrode by electropolymerization of o-phenylenediamine in the presence of myoglobin, carried out on the surface of the obtained modified nanotube electrode, followed by processing obtained th electrode with an alcohol solution of alkali.
