The present invention is directed to fluorescent protein biosensors based on oligonucleotide cross reactive sensor arrays including a selective and a non-selective protein surface binding domain for protein detection. Interaction of different protein isoforms with the sensors of this invention yields a unique optical signature for each protein. The unique optical signature allows differentiating between closely related protein isoforms and diagnosing diseases and disorders associated with the proteins also in biofluids.
