Application of the electrochemical biosensor in the detection of lactose in skimmed milk

In this work, an electrochemical approach for the quantitative detection of lactose in skimmed milk was proposed. To this end, a biosensor was developed from the immobilization of the enzyme lactase in the carbon nanotube matrix-carbon paste base. The paste from this association is deposited in the lower cavity of the working electrode, which together with the reference and auxiliary electrodes form the electrochemical cell operated from a...
