Abstract

The present invention pertains to a device and method to measure thermo-optical, preferably thermophoretic, characteristics of particles in a solution. The method comprises the steps of: (a) providing a sample probe comprising marked particles in a solution; (b) providing a temperature control system for creating a temperature gradient within said sample probe by contact heating, electrical heating and/or cooling; (c) detecting the marked particles at a first time; (d) creating a temperature gradient within the sample probe by means of the temperature control system; (e) detecting the marked particles in the sample probe at a, preferably predetermined, second time and/or at a predetermined location within the temperature gradient, and (f) characterizing the particles based on said two detections.
