Biochip and method for making same

Before or at the same time the polymerization of the prepolymer, the production method of the hydrogel biochip for coupling a plurality of probe biomolecules hydrogel prepolymer. While the hydrogel polymerization, which is micro-spotting on a solid substrate that is covalently bonded to the hydrogel in the form of micro-droplets hydrogel. Adjusting the reactivity and polymerization conditions of the prepolymer provides for effective control of the density of the probe biomolecules fixed. Biochips produced containing different biomolecules are coupled a plurality of such micro drop is useful for gene discovery, gene characterization, functional gene analysis and related studies.A bio-chip, a hydrogel, a biomolecule, a prepolymer
