Cyclic voltammetry (CV) has been used to determine the redox property of the Hb cross-linked MACys-Ru(bipyr)(2)-MACys) hapten. Three memory functions, writing, reading and erasing of the fabricated biomemory device, have been accomplished by chronoamperometry (CA) and open-circuit potential amperometry (OCPA). The reliability and repeatability of the biodevice consisting of the p(Hb-co-MACys-Ru(bipyr)(2)-MACys) sextet state bio-memory layer have been analysed. The Hb film based biodevice on gold electrodes has shown >= 2 months the retention time and switched until 10(6) times continuous cycling without degradation in efficiency. Other hand, the topography of p(Hb-co-MACys-Ru(bipyr)(2)-MACys) layer on the gold surface has investigated by scanning electron microscopy (SEM) and EDX data.eninfo:eu-repo/semantics/closedAccessBiomemory DeviceHemoglobineNanobiochipChronoamperometryPhotosensitive MonomerArticle1768591WOS:0004126101000122-s2.0-850268358722891781010.1016/j.talanta.2017.08.014Q1Q1
