Folic acid is an important water-soluble vitamin for various biological processes, and its deficiency in human organisms can lead to health problems. Different electrochemical sensors are available for detecting folic acid in various mediums. These sensors provide rapid, selective and sensitive detection of folic acid, making them a valuable tool in analytical research. The results of researchers who used low-cost and environmentally friendly materials to prepare sensors are presented in this study. The limit of detection of one such sensor was 1.8×10-10 mol dm-3 indicating its good selectivity and sensitivity.enelectrochemical sensorsfolic acidvitaminsdifferential pulse voltammetryconferenceObject
