Left: Chronoamperometric current response upon subsequent additions of urate aliquots obtained with a microbial biosensor entrapment behind a dialysis membrane; Right: urate calibration curve (-50 mV vs. Ag/AgCl). Testing solution: 30 mM Tris-HCl (pH 8.9); working volume: 20 mL; stock solution of uric acid: 10 mM in 30 mM Tris-HCl (pH 8.9).
