*3.5.3 Selectivity*

In the presence of other analytes, the interference behavior responses of the BSA/ Ab-VD2/CD-CH/ITO bioelectrode toward Ag-VD2 were observed. According to the concentrations seen in human blood, solutions containing ascorbic acid (0.1 mM), oxalic acid (1.0 mM), glucose (4.0 mM), cholesterol (4 mM), and antigen vitamin D3 (30 ng mL−1) were created. The bioelectrode for Ag-VD2 showed high selectivity for BSA/Ab-VD2/CD-CH/ITO [70].
