To make electrodes to test conductivity of MBP protein fibers containing AuNPs using a four point probe.
Areas of Pd foil used, from left to right: 35.20 mm2, 41.16 mm2, 40.18 mm2, 38.64 mm2.
Conductive epoxy did not dry overnight.
A four point probe is more accurate than a two point probe because a four point probe uses separate electrodes to carry current and measure voltage, while a two point probe combines them.
