The response characteristics of a new biosensor, which was developed by co-immobilisation of chicken liver tissue and ferrocene in a carbon paste matrix for the amperometric determination of hydrogen peroxide, was evaluated. In the range of electrode potential observed (-O.5∼ +0.05 V vs. Ag/AgCl), the bioelectrode showed the response time (t95%) as low as 13 set and the detection limit of 5.1x10-5 M, and exhibited a good selectivity in the case of the addition of the possible interferents tested. Also it offered a high biocatalytic stability and opened up the possibility for the construction of a mediatorless biosensor.
