    In this study we focused on the development of a Surface Plasmon Resonance (SPR) immunosensor for Phytophthora infestans detection. The fungus-like organism is the cause of potato late blight and is a major problem in potato growing regions of the world. Efficient control is dependent on early detection of P. infestans sporangia. The wind-dispersed sporangia are large, with a diameter range of 12-23 µm, meaning that direct sporangia capture on antibody surfaces would have a limited sensitivity in SPR assays. Here we have developed an alternative SPR immunosensor based on a subtractive inhibition assay format.
