a Schematic diagram of the fabrication process for the combinative MIPIOPs. b–d Reflection microscopic images of the lysozyme-functionalized SCCBs (b), the molecular imprinting hydrogel hybrid SCCBs (c) and the MIPIOPs (d). e–g Scanning electron microscopy (SEM) images of the microstructures of lysozyme-functionalized SCCBs (e), the molecular imprinting hydrogel hybrid SCCBs (f) and the MIPIOPs (g). Scale bars are 250 μm in (b–d) and 200 nm in (e–g). Reproduced with permission [54]. Copyright 2020, Wiley
