Abstract
An apparatus and method which print a biomolecular droplet onto a solid substrate using an electric charge concentration effect comprises: a needle shaped electric field forming electrode which is made of a conductive material, is disposed vertically, and comprises an accommodating area and a nozzle formed on a bottom end of the accommodating area; a solid substrate which is electrically grounded, is disposed below the electric field forming electrode, and comprises a moisture thin film and a target surface onto which the biomolecular droplet is discharged from the nozzle of the electric field forming electrode; and an open circuit type voltage applying unit which is electrically connected to the electric field forming electrode, applies a charge to the electric field forming electrode, and causes the biomolecular droplet to be ejected onto the target surface.
