Research results obtained in the last 3 years in the area of electroch
emical amperometric biosensors are presented. Selective electrochemica
l biosensors are proposed on the basis of investigations of electrode
materials, electrolyte content, selective properties of polymer materi
als and mediators influence. Biosensor parameters for determination of
glucose, phenol and biological oxygen demand are described. (C) 1996
