Abstract
Thin film layer of protein was developed for biomemory device consisting of myoglobin which is a metalloprotein. DTSSP molecules was utilized to immobilize myoglobin on gold substrate by chemical bond between sulfo-NHS of DTSSP and amine group of protein and self-assembly process of thiol groups of DTSSP on gold substrate. After immobilization process, the increased thickness of gold substrate was confirmed by surface plasmon resonance (SPR) and the change of morphology was investigated with scanning tunneling microscopy (STM) as a complimentary of SPR. The redox property of immobilized myoglobin on gold surface was verified by cyclic voltammetry (CV). The chronoamperometry (CA) was used in order to verify memory characteristics. The fabricated device presents successfully memory functions such as ‘write’ and ‘erase’. In these results, DTSSP modified myoglobin layer can be used to realize biomemory device.
