Objective

To make electrodes to test conductivity of MBP protein fibers containing AuNPs using a four point probe.

Description

  1. Put down conductive epoxy on Teflon surface.
  2. Put palladium wire on epoxy.
  3. Put Pd foil on top of wire and epoxy.
  4. Deposit AuNP-containing protein fibers across foils.

Data

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.

Notes

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.
