Droplet forming device and method of forming droplet using the same

A droplet forming device comprising:

• a droplet forming device including a guide part having a pillar shape in which the center thereof is empty, a central separation plate formed above the guide part and having a discharging hole formed in the center thereof, and a fluid storing part formed above the central separation plate;
• a substrate;
• and
• a plurality of pillar members formed on the substrate and having droplets formed thereon.

A method of forming a droplet, comprising:

• preparing a fluid for forming the droplet;
• preparing a droplet forming device including a guide part having a pillar shape in which the center thereof is empty, a central separation plate formed above the guide part and having a discharging hole formed in the center thereof, and a fluid storing part formed above the central separation plate;
• preparing a substrate and a plurality of pillar members formed on the substrate and having the droplet formed thereon;
• injecting the fluid into the fluid storing part to thereby form the fluid in a droplet shape at the discharging hole;
• contacting the fluid in the droplet shape formed at the discharging hole and an upper portion of the pillar member with each other;
• and
• spacing the discharging hole and the pillar member apart from each other.
