| Research Abstract |
By using chemical oscillation, we have succeeded in fabricating functional systems that can undergo spontaneous switching without any external stimuli. With coupling between pH oscillator and pH-responsive metal nanoparticles, autonomous oscillation (in other word autonomous switching) in optical properties between associated surface plasmon and isolated surface plasmon modes was appeared under CSTR condition. Furthermore, we have also succeeded in an autonomous mass transport in nanochannel by coupling between pH-wave propagation which is driven by reaction-diffusion phenomenon and nanochanel. All these results indicate that the use of non-linear chemical reacion that is the origin of self-oscillation in biology is quite useful to create an artificial system that can undergo autonomous oscillation without applying physical energy.
