Figure S1. Anisotropic conductivity of pristine GelMA and hybrid GelMA-horizontally aligned CNT gels containing different concentrations of CNTs. (A) Schematic of the systems used for horizontal and vertical measurements of electrical conductivity for hybrid GelMA-horizontally aligned CNT hydrogels. (B) Impedance measurements of pristine GelMA and hybrid gels loaded with 0.5 and 1 mg/mL CNTs. The perturbation amplitude was 25 mV. (C) I-V curves for pristine GelMA and GelMA hydrogels containing aligned and random CNTs.
