摘要
An improved electrochemical method for disassociating a biological binding partner from a corresponding second biological binding partner associated with a waveguide surface, the electrochemical method involving the application of an electrical potential to said waveguide surface (118), the improvement comprising: applying the electrical potential to the waveguide surface (118) as a square wave polarization function. Preferably, the waveguide surface is comprised of indium tin oxide. The biological binding partners are selected from the group consisting of antigen-antibody, avidin-biotin, enzyme-substrate, cell receptor-substrate/analog, antibody/anti-antibody, DNA, RNA, and fragments thereof. The antigen may be comprised of an epitope. The epitope is produced by a solid phase peptide synthesis performed on said waveguide surface (118).
