The present invention relates to a method for manufacturing a three-dimensional structure based on a block copolymer. The method comprises the steps of injecting a block copolymer (BCP) solution into each micro-well formed on the substrate and drying it to form a block copolymer layer, and applying a buffer to the block copolymer layer to hydrate the micro-well in three dimensions Forming the structure, after the three-dimensional structure is formed, injecting and curing a hydrogel solution around the three-dimensional structure may include the step of enhancing stability. In particular, the process of hydration by applying a buffer to the micro-well is performed while an electric field is applied. By controlling the concentration of the block copolymer (BCP) and the amplitude and frequency of the electric field, a three-dimensional artificial cell membrane having a desired size and shape, such as a spherical or ciliary shape and high stability (100% survival for 50 days) is manufactured can do. The present invention can be efficiently applied to various biological fields such as artificial cells, cell-mimicking biosensors, and bioreactors.
