Morphology of the chip sensor surface modified with MIP NPs. The morphology of the chip after MIP NP derivatization was investigated with AFM. The surface appeared uniformly covered with MIP NPs. The dips panel shows the SPR minima of one of the three channels before (black signal) and after (grey signal) the derivatization of the chip surface with MIP NPs. Each dip shifts to the right (higher SPR angles) when the mass increases on the corresponding sensing surface
