Microfluidics delivery systems

摘要

Methods of dispensing a small amount of liquid onto a work piece includes in some embodiments known providing a microscopic channel for the liquid to flow from the nanodispenser. In some embodiments, dispensing the liquid includes dispensing the liquid using a nanodispenser have at least one slit extending to the tip. Some methods include controlling the rate of evaporation or the rate of liquid flow to establish an equilibrium producing a bubble of a desired size.

1. A method of dispensing liquid with a nanodispenser onto a work piece in a vacuum chamber, comprising:
providing a nanocapillary having a diameter at the tip of less than 50˜m and having at least one slit cut into the nanocapillary, the slit(s) extending to the tip; and contacting the tip of the nanocapillary to the work piece surface to dispense liquid from the nanocapillary onto the work piece.
