Being the manner which generates uniform single more two molecular film beshikuru in large quantities at size of the range of 1 millimicrons or 100 millimicrons, develop the manner whose enclosure efficiency is high. This invention offers the generation device of two molecular film beshikuru. As for the generation device of two molecular film beshikuru of this invention, the structure which includes with the pulsation prevention means which are provided in the loculus and the said loculus which communicate to the multiple minute chambers and the said minute chamber aperture to the main channel and the said main channel multiple is included. This invention offers the generation method of two molecular film beshikuru. Being able to bind with the 1st water solution where as for the generation method of beshikuru of this invention, the structure of this invention and, the 1st and 2nd water solution and step and the front diagnosis separable fluid which prepare the phase separable fluid form phase separable fluid formation, as for the said phase separable fluid formation are encircled in front diagnosis separable fluid formation and the said phase separable fluid formation due to the fact that the liquid flow of the 2nd water solution inside step and the aforementioned main channel which the suspension are done shears front diagnosis separable fluid formation on the side wall surface of the aforementioned minute chamber, as beshikuruIt includes with the step which is disconnected.1μmないし100μmの範囲のサイズで均一な単一層の二分子膜ベシクルを大量に生成する方法であって、封入効率の高い方法を開発すること。本発明は二分子膜ベシクルの生成装置を提供する。本発明の二分子膜ベシクルの生成装置は、主流路と、該主流路に開口する複数の微小憩室と、該微小憩室に連絡する房室と、該房室に設けられた脈動防止手段とを含む構造体を複数含む。本発明は二分子膜ベシクルの生成方法を提供する。本発明のベシクルの生成方法は、本発明の構造体と、第1及び第2の水性溶液と、相分離流体とを用意するステップと、前記相分離流体が相分離流体層を形成し、該相分離流体層は前記微小憩室の側壁面に懸架されるステップと、前記主流路内の第2の水性溶液の液流が前記相分離流体層を剪断することによって、前記相分離流体層と、該相分離流体層に包囲された第1の水性溶液とが括れてベシクルとして切断されるステップとを含む。
