“…[13e16]. More recently, this research group has focused on the development of various electrochemical-based biomemory devices that consist of cysteine-modified azurin, cytochrome c [17,18]. However, the proposed biomemory device just displayed only one function and only one bit of information could be controlled.…”

A signal-enhanced biomemory device was developed by introducing cysteine-modified azurin/gold nanoparticle (GNP) heterolayers. The proposed recombinant azurin/GNP heterolayers provided an enhanced electron transfer between recombinant azurin/GNP and the Au surface, which stored the charges in the fabricated heterolayer. The fabricated recombinant azurin/GNP heterolayers was investigated by atomic force microscopy (AFM) and surface plasmon resonance (SPR) spectroscopy. Cyclic voltammetry (CV) was performed to examine the current signal-amplified electrochemical property. In this analysis, the recombinant azurin/GNP heterolayers produced current that was 5 times greater than the recombinant azurin monolayer. These redox potentials were then used to obtain the write step and erase step. Using these parameters, the biomemory function of the device was verified by chronoamperometry (CA).

“…Moreover, this strategy makes possible for a unidirectional electron flow from the protein to the Au surface. This heterolayer consisted of recombinant azurin and cytochrome c capable of storing the two pairs of electron, which is mentioned to as the multi-state memory [94].…”

The new concept micro devices consisting of various biomolecules have been developed in clinical, pharmaceutical, and environmental fields. Particularly, various diagnostics using biomolecule related device have been investigated and commercialized to detect specific molecules in complex matrix. In recent days, biomolecules have been employed to electronic device to generate new alternatives of silicon based nano electronics by applying natural behaviors of biomolecules. We reviewed here the bioelectronic device consisting of proteins developed by mimicking natural phenomena. We surveyed the working principle, fabrication technologies, and memory function validation of metalloprotein based biomemory device. © KSBB hÉóïçêÇëW=ÄáçÉäÉÅíêçåáÅ=ÇÉîáÅÉI êÉÅçãÄáå~åí=éêçíÉáåI=ÄáçãÉãçêóI=å~åçÑ~ÄêáÅ~íáçåI=å~åçÄáçÅÜáé= = = = =
