Figure 3

Evaluation of peformance of sensors: (a) Accuracy studies of pH sensors with standard pH samples, (b) Accuracy studies of urea sensors with different urea concentrations spiked in urine samples obtained from healthy volunteers (n = 3), (c) Interference Study for commonly present compounds in urine, (d) Accuracy studies of urea sensors with different urea concentrations spiked in urine samples obtained from kidney disease patients (n = 3), (e) Stability study and (f) Urease activity studies and leaching study of FD.
