METHOD FOR ANALYSING MACROMOLECULES, ANALYSIS DEVICE AND A METHOD FOR PRODUCING AN ANALYSIS DEVICE

摘要

The invention relates to a method for analysing macromolecules using a microarray, which consists of several spots in a known arrangement. Said spots comprise a plurality of first macromolecules that differ at least partially. The microarray is located on the surface of a solid body, preferably a chip. According to the method, at least one drop of liquid containing macromolecules is applied to the surface of the solid body, the quantity of liquid being so small that only one spot or a small group of spots of the microarray comes or come into contact with the drop of liquid. After a predetermined time has elapsed, the drop of liquid is displaced onto a subsequent spot or an additional small group of spots with the help of the transmission pulse of a surface sound wave. The spots that come into contact with the drop of liquid are then analysed to identify whether a reaction with the material of said drop has occurred. The invention also relates to a method for producing an analysis device for macromolecules. According to said method, at least one drop of liquid containing at least one type of macromolecule is applied to the surface of a solid body, preferably a chip, whereby the macromolecules have an active group that is activated during a modification of a corresponding external parameter, in order to allow bonding to the surface or to molecules that have already been bonded. The drop is displaced to a desired location on the surface with the help of the transmission pulse of one or more surface sound waves. The external parameter is modified in a homogeneous, non-local manner, permitting the bonding of the macromolecules to form the spot of a microarray, in which macromolecules from the drop of liquid are bonded to the surface. The invention also relates to an analysis device for carrying out the inventive analysis method.
