ABSTRACT:
The invention relates to methods and devices for manipulation of small amounts of liquid on surfaces, preferably on chip surfaces. According to the present invention, a quantity of liquid held together by its surface tension is applied on an area of a surface with at least one intermediate region, which borders at least in one lateral direction on a guide strip. According to the present invention, the guide strips have different surface characteristics relative to the intermediate region, such that they are more strongly wetted by a liquid, or the intermediate region is raised relative to the guide strips, whereby the height of the step is small relative to the height of the quantity of liquid.
