Abstract
What is described in this case is a laboratory microchip having microspray means whose direction of spray can be altered. The microchip has a substratewhich has a channel structure provided on one sidethereof. On the other side (in the region of an edge of the substrate in the present case), there is a microspray tip. Substrateis designed to be deformable particularly in a region, in which case the deformability may be achieved either by thinning the substrate material locally in this regionor by means of a linear perforation extending approximately perpendicularly to the plane of the paper. Alternatively, the deformability may be obtained by selecting a suitable material for the entire substrate. A microchip which has been bent in the manner indicated is shown in the bottom part of FIG.. The bending of the substrate which is shown has turned the direction of sprayof microspray tipthrough 90°. The bending of the substrate may be permanent or reversible in this case.
