Solutions
Sol A: 0.008g carbon nanoparticle in 1 mL ethanol + 5 µL surfactant Sol B: 0.015g Ferrocenecarboxaldehyde (CAS 12093-10-6) in 1mL water
Sol A and B were ultrasonicated for 10 min.
Sol C: 0.2 mL of Sol A + 0.8 mL of ethanol
Sol D: 0.5 mL of Sol B + 0.5 mL of Sol C Sol D2: portion of Sol D, which was used for tip dipping.
Sol D was sonicated for 10 min and fed to an NFP chip.
