Abstract: A multi-channel integrated microfluidic chip has at least two layers of channel structures. Each layer of channel structure is provided with a liquid phase input channel. One layer of channel structure is provided with a drop-maker unit and a collection channel. The liquid phase input channel has a liquid phase input port (1) and a resistance control unit (2). The drop-maker unit contains a multiphase emulsification channel (6) and a local resistance control unit (8). The collection channel has a washing channel (9), a washing phase input port (10) and a product output port (11). A method for preparing monodisperse gel microspheres is also provided.
