The present report describes a new phenomenon - short-term exposure of water with focused terahertz radiation of free electron laser leads to the formation of nanoparticle suspension (hydrosol). Composition of the particles formed corresponds to the material of containers used in the experiment. The present report is focused on the graphite hydrosol formation. High purity (99.5%) graphite electrode was used in the experiments. Initial material and the particles formed were investigated by atomic-force microscopy. Hydrosols are technologically convenient form, suitable for scientific and technological applications which require uniform deposition and high catalytic activity, they are useful in medicine, nonlinear optics, as well as the alternate method of sample preparation for chemical and elemental analysis.
