Abstract

The invention provides a method for measuring Young modulus of single cell based on micro-fluidic technology. According to the method, a to-be-measured cell is equivalent to an isotropous viscoelastic body, with an equivalent mechanical model of the to-be-measured cell of entering and running through a compression channel, based on a relation of a displacement of the front end of the to-be-measured of instantly entering the compression channel, the size of the cell, the Yong modules, the intensity of pressure, and the geometric parameters of the compression channel, the measurement for the Young modulus of the to-be-measured cell is realized.

Description

technical field [0001] The invention relates to the technical field of biological information detection, in particular to a method for measuring the Young's modulus of a single cell based on microfluidic technology. Background technique [0002] As the basic unit of life activities, cells contain various biomolecules that interact with each other to form a busy and orderly system. As an important functional unit of cells, the cytoskeleton participates in important physiological functions such as cell proliferation, division and deformation, and is closely related to the state of cells. Preliminary studies have shown that tumor cells with different degrees of malignancy and stem cells with different degrees of differentiation have differences in cytoskeleton functions, which are manifested in differences in cell mechanical characteristic parameters, namely Young's modulus. Therefore, the high-throughput acquisition of Young's modulus of single cells can provide a reliable me...
