    摘要: Provided is a device for printing a biomolecule solution onto a substrate using an electrohydrodynamic (EHD) effect. The device can deposit drops of the biomolecule solution with small size and volume and print more of the biomolecule solution onto a substrate, thereby enabling the manufacture of a high density biochip. The device includes a first electric field forming electrode that is shaped like a needle, is made of a conductive material, is disposed vertically, and includes an accommodating area in which the biomolecule solution is accommodated and an outlet formed on a bottom end of the accommodating area through which the biomolecule solution is discharged; a substrate disposed below the first electric field forming electrode, and including a target surface onto which the biomolecule solution discharged from the outlet of the first electric field forming electrode is deposited; a second electric field forming electrode made of a conductive material and disposed below the first electric field forming electrode; and a voltage applying device which is electrically connected to the first and second electric field forming electrodes to apply a voltage between the first and second electric field forming electrodes so that an electric field is generated around the biomolecule solution suspended in the outlet, wherein, due to the interaction between the electric field and a difference between dielectric constants of the biomolecule solution having a free surface and the surrounding atmosphere, the electric force acts inward on the biomolecule solution, thereby causing a predetermined amount of the biomolecule solution to drop onto the target surface of the substrate.
