For efficient detection of target proteins, we aimed to create an array of biosensors. In this study, we integrated 4×4 cantilever sensors and developed a microfluidic device for manipulating liposome and α-synuclein solutions to be introduced on the cantilevers by using a 3D printer. The width and height of the channels were 500 μm and 100-600 μm, and the diameter of each sensor cell was 2 mm. 3D printing process enabled us to fabricate the molds in a short time of about 1 hour. Based on the results of the flow path by the conventional method, the pressure and the thickness of the flow path will be changed to control the solution.
