Abstract

The invention relates to a biological macromolecule optical detection method related to intracellular colloid osmotic pressure, and construction and applications of a drug screening method related tothe biological macromolecule optical detection method. According to the present invention, the size, the shape, the position and the number of myosin, tubulin and other biological macromolecule particles or particle aggregates rich in cells or the density and the strength of protein markers are subjected to optical detection or imaging detection so as to evaluate the change of the intracellular colloid osmotic pressure and the regional mapping; with the optical detection method for the biological macromolecules related to intracellular colloid osmotic pressure, the change of the intracellularcolloid osmotic pressure can be analyzed, and the compositions and the functions of the crystal osmotic pressure and the colloid osmotic pressure in the intracellular colloid osmotic pressure can be analyzed by combining the method and the osmometer.

Description

technical field [0001] The invention relates to a biomacromolecule optical detection method, in particular to the construction and application of a biomacromolecule optical detection method related to intracellular colloid osmotic pressure and a related drug screening method. Background technique [0002] Chemical, electrical and mechanical activities are the basic forms of cell life activities. Although the former two have been studied in depth, intracellular mechanical activities have received little attention, which is a blind spot in the current cell research field. A variety of physiological and pathological activities of cells depend on their internal mechanical activities, such as cell growth and division, shrinkage, edema, differentiation, neural polarization, invasion and metastasis of malignant tumors, etc. Cell morphology changes must be the result of internal mechanical stretching. [0003] Although the microfilament and microtubule pulling forces based on motor ...
