Cytochrome c/silver nanoparticle hetero-layer film to enhance electrochemical signal for information storage device |
| 초록 |
In this research, silver nanoparticle is introduced to cytochrome c layer to enhance electrochemical signal. Electrochemical signal enhancement of biomolecules is essential to acquire the enhanced memory property. The hetero-layer film composed of cytochrome c and silver nanoparticle was fabricated on Au substrate via chemical linker. The electrochemical property investigation of hetero-layer film was verified by cyclic voltammetry (CV) and surface topology of film was investigated by atomic force microscopy (AFM). Finally, to verify enhanced memory function of fabricated film, chronoamperometry (CA) was used. From experimental data, the fabricated hetero-layer film showed the enhanced electrochemical-signal and memory function compared to cytochrome c homolayer without silver nanoparticle.
