Different levels of interpenetration of poly(hydroxymethyl‐3,4‐ethylenedioxythiophene) (PHMeDOT) inside a poly‐γ‐glutamic acid (γPGA) biohydrogel matrix, previously loaded with microparticles of poly(3,4‐ethylenedioxythiophene) (PEDOT), have been obtained. The degree of interpenetration has shown influence on the morphological and electrochemical properties of the resulting biohydrogel ([PEDOT/γPGA]PHMeDOT) with a maximum after 1 h of PHMeDOT polymerization time. The high biocompatibility of all biohydrogel components, together with the combination of mechanical properties of γPGA hydrogels with the electrochemical properties of interconnected microparticles of PEDOT, makes it a promising material for next generation of biosensors.
