1. a method for preparing biochip comprises the steps:

  • the inkjet water-soluble ink of containing metal nano particle is printed micro-nano metal array pattern by ink-jet printer in substrate;

    Solidify the back to the sterilising treatment that carries out disinfection of the substrate with described array pattern, and then carry out common cultivation, obtain described biochip with biological substance;

    The inkjet water-soluble ink of described containing metal nano particle prepares according to following method;

    metal nanoparticle, water-soluble cosolvent, macromolecule dispersing agent, interfacial agent and redistilled water are mixed, through pre-dispersed, concentrate, obtain the inkjet water-soluble ink of containing metal nano particle;

    Wherein, the inkjet water-soluble ink of described containing metal nano particle is made up of the material of following quality percentage composition;

    1%~

    25% metal nanoparticle, 10%~

    50% water-soluble cosolvent, 0%~

    20% macromolecule dispersing agent, 0%~

    20% interfacial agent, 25%~

    75% redistilled water;

    Described metal nanoparticle is water-soluble gold nano particle, water-soluble silver nano particle or water-soluble platinum nano particle;

    Described water-soluble cosolvent is hexanaphthene, methyl alcohol, ethanol, 2-propyl alcohol, two-1,2-propylene glycol, Diethylene Glycol, triethylene glycol, ethylene glycol, propylene glycol, butyleneglycol, pentanediol, hexylene glycol and contain a kind of in the polyvalent alcohol of at least three hydroxyls or greater than more than one mixture.
