pH dependence of non-specific adsorption and detection solution in electrochemical metalloimmunoassay using antibody–silver nanoparticle conjugates
The pH dependence of non-specific adsorption of antibody–silver nanoparticle conjugates (AgNPs–Ab) to an antibody-immobilized electrode was investigated. The adsorption was promoted at lower pH values (pH 3.0) and inhibited at higher pH values. These results are attributed to the zeta potential of t...
