| 摘要 |
The present invention provides a membrane based biosensor. The biosensor includes an electrode and a passivating layer bound to the electrode. A lipid membrane incorporating ionophores, the conductivity of the membrane being dependent on the presence or absence of an analyte, is bound to the passivating layer in a manner such that an ionic reservoir exists between the membrane and the passivating layer. Reservoir spanning molecules spanning the ionic reservoir are also included. These molecules are covalently attached at one end to the membrane and at the other to the passivating layer. The incorporation of the passivating provides greater stability to the sensor.
