Abstract: A system, method, device, and process for making and using an electromagnetic-sensitive biosensor on a biosensor disk to identify and classify an analyte in a sample. The biosensor of the biosensor disk is exposed to a sample containing analytes and a desired analyte adheres to the biosensor. The biosensor disk is rotated during operation and an electromagnetic emitter directs an electromagnetic radiation beam at the biosensor disk. The returned electromagnetic radiation from the biosensor disk is received by a sensor that converts the returned electromagnetic radiation into a signal to indicate the presence of the desired analyte in the sample.
