Abstract

A fluid driving method based on algae cells specifically comprises the following steps that (1) a viscous micropump is designed, and the viscous micropump comprises a fluid driving chip, an L-shaped adapter plate, a three-dimensional nanometer moving platform, a microscope, a CCD, a high-precision Z-direction displacement table, a projector, a focusing objective lens, a signal generator and a computer; (2) slowly injecting the treated algae cell solution into a micro-pipeline in a fluid driving chip from a fluid inlet; (3) projecting a light spot to the lower surface of the fluid driving chip; (4) adjusting the focal plane of the focusing objective lens and the focal plane of the microscope; (5) adjusting the size of the light spot, and enabling the signal generator to generate a sinusoidal signal to act on the fluid driving chip; (6) capturing autorotation algae cells in the micro-pipeline by using light spots and moving the algae cells; and (7) removing redundant algae cells from the micro-pipeline. According to the invention, the driving of the fluid is completed by using the rotating algae cells, and external extra energy is not needed.

Description

technical field [0001] The invention relates to the technical field of biological fluid drive, in particular to a fluid drive method based on algae cells. Background technique [0002] Micro-total analysis system, also known as lab-on-a-chip, has been widely used in chemistry, life science and microelectronics since it was proposed. The micro-analysis system can be used as a micro-filter to filter and collect tiny particles. It can also be used as a micro-mixer for mixing samples and analytes in the fields of chemistry and biology. It can even be used as a micro-reactor for polymerases. chain reaction. In order to realize the application mentioned above, in the micro-analysis system, it is often necessary to integrate some functional components, including: flow sensor, micro-valve, and micro-pump. Among these functional components, the micro-pump is the most critical element. The micropump can be used to drive the controllable transport of fluid in the micro total analysis...
