Abstract
A laboratory microchip providing a microspray has a substrate having a channel structure on one side thereof. A microspray tip is on the other side of the substrate close to an edge of the substrate. The substrate is deformable in a particular region. Deformation results from thinning the substrate locally in the region or by providing a linear perforation that extends approximately perpendicular to the plane of the substrate. Alternatively, deformation can be obtained by selecting a suitable material for the entire substrate. Substrate deformation can be permanent or reversible.
