Abstract
The invention generally relates to an apparatus and a method for mixing of liquids (50) or of particles with a liquid (50). In a volume of liquid (50), a thermal convection flow is generated at at least one surface of the volume of liquid by irradiating IR radiation (30) into the volume of liquid. Thereby it is possible to avoid a depletion zone at the surface and to more accurately measure interactions of the particles with the surface by means of surface-based measurement methods.
Claims23
Method for mixing liquids (50) or particles with a liquid (50), comprising the steps:
- a. providing a volume of liquid (50);
- b. generating a thermal convection flow at at least one surface/boundary surface of the volume of liquid by irradiating electromagnetic radiation (30) into the volume of liquid.
Method for analyzing molecular interactions at and/or in a thin film (80) in a volume of liquid, comprising the steps of:
- providing, on an object carrier or a sample chamber (45), at least one volume of liquid (50) with particles present therein, and irradiating electromagnetic radiation into the volume of liquid (50) according to any one of the preceding claims for generating the thermal convection flow,
- measuring a specific or unspecific interaction of the particles with a surface/boundary surface of a sample chamber or an object carrier,
- characterizing the interaction of the particles on the basis of the measurement.
