Noncovalent antibody immobilization on porous silicon combined with miniaturized Solid-Phase Extraction (SPE) for array based immunoMALDI assays
This paper presents a new strategy to combine the power of antibody based capturing of target species in complex samples with the benefits of microfluidic reverse phase sample preparation on an integrated sample enrichment target (RP-ISET) and the analysis speed of MALDI MS. The immunoaffinity step is performed on an in-house developed 3D-structured high surface area porous silicon (PSi) matrix, w
