HFCD film band with permselective properties for low molecular biologically active substances, electrochemical sensor and method of determining these substances

摘要

The solution subject is electrosynthesis compact layer of 2,2'-bis [4,5-bis (4-hydroxybenzyl) -2- (4-hydroxyphenyl) cyclopent-4-ene-1,3-dione] of electrodes of carbon ( glassy carbon, carbon fiber), gold, platinum and similar solid electrodes. Acquired permselective layer may be used in the manufacture of electrochemical sensors and can provide their selectivity. Electrosynthesis is based on polarization of the electrodes cyclically constant or changing potential of 600-1000 mV (vs. Ag / AgCl) in the supporting electrolyte (pH 7-14), which contains the above derivative bis (cyklopentendionu).
