Patent Title: Sensor
Publication date: 2008
Publication number: WO/2008/107649
Abstract: This invention relates to a sensor and in particular to a sensor for the detection of biologically important species. Specifically, the invention provides a method for detecting an analyte in the presence of at least one interferent in a sample. The method comprises the steps of providing a sensor having a transducer and a receptor layer in communication with the transducer, in which the receptor layer comprises a material for absorbing the analyte; exposing the receptor layer to the sample; treating the receptor layer to remove selectively the at least one interferent; and measuring the signal from the transducer. The treatment step is performed by applying a change in potential, a change in pH or a change in temperature to the receptor layer, by washing the receptor layer, by irradiating the receptor layer, or a combination thereof.
