Yes, but keep in mind that showing superconductivity on very small samples is hard. You never actually measure 0 resistance - you measure a resistance at the limit of your equipment sensitivity.
The smaller the sample, the smaller the resistance is even if it's not superconducting, and all sorts of other effects come into play - i.e. your wires and leads have a resistance you need to account for, parasitic inductance and capacitance climbs etc.
