A radio frequency based sensor is provided. The sensor comprises a radio frequency identification tag having a substrate, where the radio frequency identification tag generates an associated electromagnetic field. The sensor further includes an analyte recognition element in operative association with the substrate, where the analyte recognition element is capable of binding to a target analyte, and a signal amplification entity coupled to the analyte recognition element, where the signal amplification entity facilitates change in electromagnetic field in presence of the target analyte. |
