Provided are a device (100) and method for printing biomolecules on a substrate (30) using an electric charge concentration effect. The device (100) enables the limitation of the material and surface characteristics of a substrate (30) to be overcome, enables the accurate dropping of a biomolecular droplet onto a target surface (31) of the substrate, prevents electric discharge, and thus allows the manufacturing of a high density biochip by depositing numerous biomolecular droplets small in size and volume onto a substrate (30). The device including: a needle-shaped electric field forming electrode (20); a substrate (30) that is disposed below the electric field forming electrode (20), is grounded, and includes a target surface (31); and an open circuit type voltage applying unit (50) which supplies first electric charges to the electric field forming electrode so that the biomolecular droplet drops onto the target surface (31) of the substrate. |
