Bioanalytical characteristics of the constructed bionanosensors GhOx/nCeAu/GCE (a,b), GhOx/nAuHCF/GCE (c,d), GhOx/nCuFe/GCE (e,f) and GhOx/HRP/GCE (g,h) at −250 mV: chronamperometric current responses (a,c,e) and corresponding calibration curves (b,d,f) upon additions of CHOL (an electrode area of 7.06 mm²).
