Capture And Release

<p>We present a polyelectrolyte brush electrode with high-capacity for protein immobilization that captures and releases proteins by an electrochemical potential. Central to our concept is the use of polyelectrolyte brushes that switch reversibly by electrochemistry. Our electrode enables high-fidelity control of protein species in space and time. We predict several application areas for this technology; for instance in protein separation and in biomedical devices.</p>

Abstract We use a quartz crystal microbalance with dissipation (QCM-D) to investigate the swelling/de-swelling and hysteresis in brushes of weakly ionizable polyanion poly(acrylic acid) (PAA) brushes and bilayers containing a PAA brush and a poly(ethylene imine) (PEI) overlayer [...]
