A method for the preparation of novel lactate biosensing strip by depositing a pair of silver layers on an electrically insulated base support by any conventional method; depositing a pair of graphite layers on said layers by any conventional method, each of said silver layers being deposited with one graphite layer a first graphite layer completely covering the first silver layer, and the second graphite layer covering the second silver layer only in part of the surface thereof that is away from the surface facing the base support; depositing a silver chloride layer on the second silver layer on the part thereof that is not deposited with a graphite layer to obtain a silver/silver chloride electrode; adsorbing physically lactate oxidase enzyme with an electron mediator on the first graphite deposited silver layer to obtain a working electrode; and applying an outer hydrophilic membrane on the above said first reference electrode and second working electrode to obtain the desired pair of electrodes on an electrically insulated base support in a single assembly.
