The research hotspot of biochip is transferring from passive chip to initiative chip

and the electroanalysis technology shows prominent technology advantage in this process.Nano-materials are very sensitive to the change of environment for their huge interface.All of temperature

light

humidity or ambience variety will change electron transfer state and nano-materials interface with rapid and sensitive response

which indicates the nanomaterial are one of the best fixed materials for making efficient biosensor and biochip.The biomimetic films made from nanomaterial are propitious to both the bioactivity maintenance of protein（anzyme） and the superiority exertion of rapid electron transform and high sensitivity in the interaction between nanomaterial and protein.Results show there will be great application for nanotechnology and electralysis in biochip development.
