The goal of this experiment is to test the conductivity of MBP protein fibers containing AuNPs was tested using electrodes and a four point probe.
The resulting probe is as pictured:
The key advantage of four-terminal sensing is that the separation of current and voltage electrodes eliminates the impedance contribution of the wiring and contact resistances.
