Formation of droplet or hydrogel arrays using hydrophilic-hydrophobic patterned surfaces for high-throughput screening applications

摘要

The present invention relates to a method of forming an array of separated homogenous fluid microdroplets or hydrogel micropads of a desired shape and size in a desired spatial pattern, comprising the steps of providing a patterned substrate with a solid support coated with a porous polymer layer or film comprising hydrophilic areas having the desired shape and size, surrounded by hydrophobic areas separating the hydrophilic areas into the desired spatial pattern, and applying the fluid to a multitude of the hydrophilic areas at the same time.
