Development of a highly sensitive voltammetric sensor for the detection of folic acid by using MoS and ionic liquid-modified carbon paste electrode.

Background And Purpose: Sensitive analytical determination of folic acid is important in clinical laboratories due to its versatile biological functions.

Experimental Approach: A simple folic acid sensor was successfully fabricated based on two-dimensional transition metal dichalcogenide MoS modified carbon ionic liquid paste electrode (MoS-CILPE). The electrochemical properties of the fabricated electrode were investigated by cyclic voltammetry (CV), differential pulse voltammetry (DPV), and chronoamperometry.
