ObjectiveWe prepared all the materials to perform a four probe method. This method will allow us to determine the resistivity of the filaments we obtained after our first Gold NPs syntheses. To measure the resistivity of a material, two methods can be use. Each of them permit to perform absolute measurement without using calibrated standards:

Protocol
We notice that the foils 2 and 3 have to have an area as closed as possible; the foils 3 and 4 will be used as references. At the end, the four Paladium compounts must not be in contact between each other (neither by direct contact; neither through the Epoxy). Conductive Epoxy (Chemtronics) is a silver compount which provides excellent electrical conductivity and high thermal conductivity; we are using it to make high-strength solderless conductive connections.
