We present a novel surface plasmon resonance (SPR) biosensor for detection of human interferon gamma (hIFNy), an important diagnostic marker for several infectious diseases. The biosensor employs engineered proteins derived from albumin binding domain (ABD) and selected with ribosome display to provide high affinity towards hIFNy. We demonstrate that the biosensor provides rapid, sensitive, and cost-effective platform for the detection of hIFNγ and allows its detection at nanomolar levels both in buffer and diluted human plasma
