TI  - Protein-based multi-bit biomemory device consisting of various metalloproteins on 
      self-assembled 11-MUA layer.

AB  - A multi-bit biomemory device was devised by introducing 4 different 
      metalloproteins (azurin, cytochrome c, ferredoxin, myoglobin) to an electronic 
      device using 11-MUA (11-mercapto-undecanoic acid) as the chemical linker. The 
      immobilization of the 4 different self-assembled protein layers on a Au substrate 
      via 11-MUA were confirmed by Raman spectroscopy and atomic force microscopy 
      (AFM). The redox properties of these 4 different protein layers immobilized onto 
      Au surface were assessed by cyclic voltammetry (CV). In addition, their memory 
      functions were verified by chronoamperometry (CA). Based on these results, we 
      demonstrated that a multi-bit biomemory concept could be realized using various 
      metalloproteins as active materials.
