Abstract: The invention relates to a device for orienting at least one object in at least a first or a second orientation or for placing it in a first or a second spatial location, comprising: a substrate (10) having a surface (10a), at least one object (3) levitated above said surface (10a),wherein the device (1) is designed to generate an e.g. electrostatic potential with help of the substrate (10) for trapping the at least one object (3), the potential having at least a first minimum and a second minimum, so that the at least one object (3) is oriented in the first orientation (or located in a first spatial location) when being trapped in the first minimum, and in the second orientation (or located in the second spatial location) when being trapped in the second minimum, and wherein said at least one object (3) is trapped in one of said minima.
