The eznyme biosensor(EB) as a sort of biosensors are widely used analyse target substances from samples of medicine, environment and food processing in recent years. During the EB preparation, effective immobilization of enzyme is a key step related with the activity of enzyme and the lifetime of EB. In current research, a method to determine nonylphenol(NP) contents in the water samlples has been developed on the base of laccases cetyltrimethyl ammonium bromide -carbon paste electrode. The experimental results showed that the EB developed in this optimized conditions, its minimum detectable limit could reach 0.2µg／L, and the recovery was in the range from 91% to 109% at the concentrations form 3.0×10-4 mol.L-1 to 5.0×10-6 mol.L-1. The sensor is perfect which is convenient, effective, and cheap and really can be used practice.
