Flexible electrochemical sensor for highly sensitive and selective non-enzymatic detection of creatinine <i>via</i> electrodeposited copper over polymelamine formaldehyde

Abstract

. Moreover, the sensor was applied to real samples of serum creatinine and recoveries of 97 to 114% were found. Additionally, a paper-based flexible screen-printed electrode was fabricated which displayed an excellent activity with the same detection range of 100 fM-60 mM and long-term storage stability of 15 days.
