Surface properties of n-type films. (a) Water contact angle and (b) ζ potential of the n-type polymer films. Error bars represent the standard deviation of (a) nine and (b) four different measurements. (c) Orientations of native GOx from A. niger (PDB: 3QVP) as a function of surface charge: (i) “front-lying” orientation on a charge-neutral surface; (ii) “standing” orientation on a positively charged surface; and (iii) “back-lying” orientation on a negatively charged surface. Surface colors on GOx indicate positive and negative electrostatic potentials contoured from 50 kT/e (blue) to −50 kT/e (red). The cofactor is shown in stick representation and highlighted in red.
