Abstract

The invention belongs to the technical field of tissue engineering and biomanufacturing subordinate to biomedical engineering, and particularly relates to a microfabricated gas matching layer modulated bulk ultrasonic cell assembly and arrangement device, preparation method and application. The microfabricated gas matching layer modulates the method and device for assembling and arranging bulk ultrasonic cells of the present invention. The acoustic field generated by the ultrasonic transducer is modulated by processing the acoustic matching layer micropattern structure, and the cells are assembled in the cell assembly chamber. and any arrangement. For the first time, this device uses soft lithography to process an acoustic matching layer to modulate the sound field for cell assembly, and realizes a more flexible volumetric ultrasonic sound field pattern, making it more suitable for various biological research and tissue engineering. Application prospects and business value.

Description

technical field [0001] The invention belongs to the technical field of tissue engineering and biomanufacturing subordinate to biomedical engineering, and particularly relates to a microfabricated gas matching layer modulated bulk ultrasonic cell assembly and arrangement device, preparation method and application. Background technique [0002] In the field of tissue engineering, the orderly assembly and manipulation of cells plays an increasingly important role in controllable cell growth. Because many cells communicate and function based on certain shape and structure signals, in order to achieve specific tissue functions And to guide a specific differentiation direction, it is necessary to arrange and assemble samples such as cells according to a specific structure. Most of the traditional cell arrangement methods use molds for passive cell solution arrangement. This method can only arrange cell solutions and cannot directly act on cells of smaller size, and the substrate w...
