NOVELTY - Preparing gold nanoparticle template, comprises jetting the inkjet water soluble ink containing gold nanoparticle on a printer to print micro-nano gold array pattern on a substrate, and curing, calcining or laser-etching the substrate with the array pattern to obtain gold nanoparticle template, where the inkjet water soluble ink containing the gold nanoparticle is prepared by ultrasonically mixing gold nanoparticle, water soluble co-solvent, a polymer dispersant, a surfactant and doubled distilled water, and pre-dispersing and condensing, and gold nanoparticle is water soluble nanoparticle.    USE - The gold nanoparticle template is useful for preparing a cell chip, which is a neuronal cell, a cervical carcinoma cell HeLa, a human embryonic cellulose forming cell (embryonic skin fibroblast), breast cancer cell MCF7, human chronic promyelocytic leukemia cell K-562, mouse embryonic cell NIH/3T3 or hamster ovary cell (Chinese hamster ovary) (all claimed).    ADVANTAGE - The method: prepares the template for synthesizing the chip in a simpler, easier and faster manner with a rapid detection property; and is ecofriendly and economical.    DETAILED DESCRIPTION - Preparing gold nanoparticle template comprises jetting an inkjet water soluble ink containing gold nanoparticle on a printer to print micro-nano gold array pattern on a substrate, and naturally curing, calcining or laser-etching the substrate with the array pattern to obtain the gold nanoparticle template, where the inkjet water soluble ink containing the gold nanoparticle is prepared by ultrasonically mixing (in wt.%) the gold nanoparticle (1-25), water soluble co-solvent (10-50), a polymer dispersant (0-20), a surfactant (0-20) and doubled distilled water (25-75), and pre-dispersing and condensing, where the gold nanoparticle is a water soluble gold nanoparticle, and the water soluble co-solvent is cyclohexane, methanol, ethanol, 2-propyl ethanol, 1,2-propylene glycol, diethylene glycol, triethylene glycol, propylene glycol, butanediol, hexylene glycol or polyatomic alcohol containing at least three hydroxide radicals. An INDEPENDENT CLAIM is also included for the gold nanoparticle template prepared by the above mentioned method.
