摘要
As a basic technology, dispensing liquid into small droplets is widely used in many nowadays technologies, such as 3D printing [I-4], biological/chemical patterning [5-7], and drug discovery [8,9]. Traditional transfer methods by pipette or pin, which may date to 4000 years ago [10], are simple and cheap to generate droplets bigger than μ100 pm [11] for most materials.
