Abstract (en)
[origin: WO02085520A2] The invention relates to methods and devices for manipulating small amounts of liquid on surfaces, preferably on chip surfaces. According to the invention, an amount of liquid, which is held together by the surface tension thereof, is placed onto an area of a surface having at least one intermediate area that, at least in a lateral direction in space, abuts against a guide strip. Either the guide strips have a surface condition, which differs from that of the intermediate area in that they are made wetter by a liquid or the intermediate area is elevated with regard to the guide strips, whereby the height of the step is small compared to the height of the amount of liquid.
[origin: WO02085520A2] The invention relates to methods and devices for manipulating small amounts of liquid (1) on surfaces, preferably on chip surfaces. According to the invention, an amount of liquid, which is held together by the surface tension thereof, is placed onto an area of a surface having at least one intermediate area (3, 4) that, at least in a lateral direction in space, abuts against a guide strip (5, 6). Either the guide strips (5, 6) have a surface condition, which differs from that of the intermediate area (3, 4) in that they are made wetter by a liquid or the intermediate area (3, 4) is elevated with regard to the guide strips (5, 6), whereby the height of the step is small compared to the height of the amount of liquid (1).
