Increasing the pH gives rise to two opposing effects : ( 1 ) increased oxidation of Dopa , thus , decreasing availability for the Dopa - mediated adhesion , and ( 2 ) increased bidentate Dopa - Ti coordination , leading to the further stabilization of the Dopa group and , thus , an increase in adhesion force .
