Abstract

AbstractThe bioelectrocatalytical properties and kinetic characteristics of new oxidase biosensors based on two different carbosilane dendrimers are described. The best glucose biosensor developed displayed, in an ascorbate interference free work potential interval, a strictly linear range from 0 to 4.0 mM, a detection limit of 40,6 μM and a response time less than 3 s. The lactate biosensor displayed a linear range from 0 to 0.8 mM, a detection limit of 0.73 µM and a response time less than 2 s. The apparent Michaelis–Menten constants were calculated to be 4.39 mM and 2.08 mM respectively, according to Lineweaver–Burk equation.
