Fig. 6From: Surface plasmon resonance based on molecularly imprinted nanoparticles for the picomolar detection of the iron regulating hormone Hepcidin-25MIP NP SPR sensor response to Hepcidin-20. Hepcidin-20 was injected at increasing concentration in the sensor. The response to Hepcidin-20 was not proportional to the injected concentration, indicating the selectivity of the sensorBack to article page
