We report on the design and testing of photonic biosensors for the type-selective detection of different types of matrix metalloproteinases (MMPs). The ability to detect a panel of different MMP types has important implications for prognosis of wound healing. We combine the immunocapture of MMPs on dispersed magnetic nanoparticles modified with antibodies specific for target MMPs (immuno-magNPs) with subsequent MMP detection upon fluorogenic peptide cleavage in porous silicon resonant microcavity (pSiRM) architectures. We report fast, sensitive, and type-selective detection of MMPs directly in wound fluid. This study sets the scene for downstream developments of multiparametric biosensors as point-of-care (POC) prognostic tools that may step-change chronic wound management.
