Solid-phase surface and solution motion mode and motion device

Abstract

The present disclosure provides modes of relative motion between a solid surface and a solution, and the related motion apparatuses. In an interaction between the solid surface and a target object, the target object is dissolved or dispersed in the solution, and the solid surface and the solution make a relative motion, with the relative motion including a relative movement perpendicular to the solid surface, in order to improve at least one of the following: binding rate, dissociation rate, binding uniformity, binding directionality and binding density of the target object to the solid surface. Compared with the traditional modes of relative motion in which the relative motion is parallel to a sensor surface, the modes of relative motion of the present disclosure can effectively improve the binding efficiency and dissociation efficiency between a ligand and an analyte given the same relative motion velocity between the sensor and the solution.
