Device for generating freely definable libraries of elements in the form of ligand and acceptor structures for combinatorial synthesis, for example in active ingredient research

摘要

The invention relates to a device for generating freely definable libraries of elements (8; 34; 54) in the form of ligand and acceptor structures for combinatorial synthesis, for example in active ingredient research. Said elements are regularly arranged on a substrate (6; 30; 50) along a first and a second coordinate (10; 36; 54 or 12; 38; 58) and a dosing head (14; 42) comes into contact with each element separately and in a controlled manner. In each position the dosing head places a metered quantity of a reagent or solvent onto a corresponding element. The substrate (6; 30; 50) is configured as a rotating body which can be turned about its axis of rotational symmetry (2; 32; 52), which serves as its axis of rotation, in the direction of the first coordinate (10; 36; 54). At least one dosing head (14; 42) can be displaced in relation to the substrate along the second coordinate (12; 38; 58) and parallel to the surface of the substrate, and can be controlled in accordance with its momentary position so as to release a defined quantity of the relevant reagent or solvent.
