The invention provides a method for synthesizing nonspherical hydrogel microparticles. In a first stage, oil-in-water droplets are formed by adopting a T-channel structure; and in a second stage, oil / water / oil double emulsion is formed by adopting a flow focusing structure. Under the irradiation of ultraviolet light, the intermediate phase of the double emulsion is polymerized to form the hydrogel microparticles, and polymerization reaction on an interface of an external phase and the intermediate phase is suppressed, so that hydrogel cannot wrap internal-phase oil cores, and the hydrogel microparticles taking the internal-phase oil cores as templates are formed. The method has the advantages that: the volume velocity ratio of the internal phase to the intermediate phase is controlled to form a series of hydrogel microparticles with similar shapes; the number of internal cores of single double emulsion is controlled to form hydrogel microparticles with different shapes such as meniscal shapes and polypod shapes; additives in a monomer solution are controlled to form hydrogel microparticles with special functions such as fluorescence and magnetism; and compared with microparticles formed by a photoetching method, the microparticles formed by the method have three-dimensional shape structures.
