The interaction of a corticosterone antibody and glutaraldehyde adsorbed on a Pt electrode modified with silane was examined by cyclic voltammetry. A mirror-polished Pt wire was oxidized for 10 min at +1.3 V vs.Ag/AgCl in 1,0 M H2SO4. The oxidized Pt wire was coated with 3-aminopropyltrimethoxysilane under N2gas for 1 h at room temperature in benzene, and then modified with glutaraldehyde. The modified electrodes were tested for their electrocatalytic properties and interaction with the corticosterone antibody. The cathodic peak currents (-0.4 V) exhibited a reproducible linearity of the current intensity vs.the concentration of anticorticosterone. |
