Performance in an interference test with protein factor. (A) The microfabricated electrodes were compared with two PCB electrodes using 5 mM NaCl solution spiked with BSA interference solution (0–20 mg/mL). (B) Six concentrations of standard NaCl conductivity solutions measured using the portable sensing system and PCB electrode.
