Immobilization of expressed proteins on EEG-based electrodes based on their molecular structure. (a) Schematic representation of the expected orientation of proteins C-LHCA4 and N-LHCA4 (driven by the 10xLeu tag) when covalently bound to –COOH groups on the surface of EEG-based electrodes through the 10xLys tag. Photo-active region in each case is represented by green dots on the molecular structure. (b) Immobilized C-LHCA4 and (c) N-LHCA4 on EEG-based electrodes under fluorescence microscopy.
