17 Sensors in Medicine 2020 Results Conclusions ✓ Both Cu/Naf/Au and CuO/Au show a creatinine-specific response ✓ Sensors have negligible responses to high concentrations of glucose ✓ Limits of detection and dynamic ranges for both approaches suitable for detection of clinical levels of creatinine ✓ Both approaches merit further investigation and optimisation Fig. 1.
