“…The blends of conductive polymers and bio-macromolecules are of complexity in their multi-level and multi-dimensional structures, including heterogeneities in composition, phase geometry and interface morphology. Even in the mono-phase of conductive polymers, it is still of complex and heterogeneous structures in dispersive dimensions, in packed or entangled polymer chains and even in single chains [3,4]. The complexity in structures leads to the difficulties to investigate the distribution and displacement of the charge carriers along or among the polymers chains, and the difficulties to illuminate the working mechanism of the bio-devices and to repeat or to enhance the device performance.…”
