NOVELTY – The multi-component amperometric phenolic compounds biosensing system comprises a multi-variation calibration assembly (PCA and PLS) for simultaneous quantification of different compounds. The enzymes laccase (raw extract) and tyrosinase are immobilised in carbon fibre electrodes by carbodiimide and glutaraldehyde, and a multi-channel potentiostat is employed. EMBODIMENT – Thus e.g. phenol and chlorophenol can be sensed in clinical and environment work. USE – In instrumentation.
