Abstract

The invention provides a cell suspension concentration sensor, a detecting system and a detecting method thereof. The cell suspension concentration sensor comprises a metal outer shell, an acoustic surface wave resonator and a silk-screen printing carbon electrode, wherein the acoustic surface wave resonator is packaged into the metal outer shell in a vacuum mode; the acoustic surface wave resonator adopts ST (system test) cut quartz as a piezoelectric substrate material, and through the preparation by a photoetching technology, the frequency of emitted acoustic surface wave is 433MHz. The cell suspension concentration sensor provided by the invention is small in volume, practical and convenient, rapid in electrode response and high in flexibility, has the advantages of good bath repeatability, low cost and the like, also can achieve high frequency, and can detect cell suspension concentration to be detected rapidly in real time.

Description

technical field [0001] The invention relates to a sensor, in particular to a cell suspension concentration sensor. Background technique [0002] Cell suspension refers to the digestion and blowing of adherent cells with trypsin, etc., to separate the cells from each other, so that the cells are suspended in the culture medium. There is currently no method for directly measuring the concentration of a cell suspension. Usually, a certain number of cells is taken out, and then the number of cells is observed through a microscope, and then an appropriate amount of solvent is added by calculation to prepare a cell suspension of a certain concentration. To obtain other concentrations of cell suspension, it is necessary to dilute the high-concentration suspension to a low concentration, or concentrate the corresponding low-concentration suspension to a high concentration. When a cell suspension with an unknown concentration is obtained, the existing detection method cannot direct...
