Abstract: The invention relates to a method for controlling the movement of an Abrikosov vortex of an element consisting of a supraconductive material, a so-called supraconductive element, comprising a step of inhomogeneously heating the supraconductive element with the Abrikosov vortex in a heating zone in such a way as to move the Abrikosov vortex towards the heating zone.

Abstract: A method and device for photothermal imaging tiny metal particles which are immersed in a given medium like a living cell. The given medium and immersed tiny metal particles are illuminated through separate phase reference laser beam and sensitive probe laser beam, with the sensitive probe laser beam undergoing through impingement on the given medium slight phase changes induced by photothermal effect due to a local heating thanks to a heating laser beam, in the absence of any substantial phase changes to the phase reference laser beam. Illuminating is performed by focusing the separate phase reference laser beam. The induced slight phase changes on the sensitive probe laser beam with reference to the phase reference laser beam are detected through differential phase interference contrast phenomenon so as to allow each of the tiny metal particles in the given medium to be imaged as an optical label.

Abstract: A method and device for photothermal imaging tiny metal particles which are immersed in a given medium like a living cell deposited onto a transparent glass slide. The given medium and immersed tiny metal particles are illuminated through separate phase reference laser beam and sensitive probe laser beam, with the sensitive probe laser beam including a heating laser beam undergoing through impingement on the given medium slight phase changes induced by photothermal effect due to a local heating, in the absence of any substantial phase changes to the phase reference laser beam. Illuminating is performed by focusing the separate phase reference and sensitive probe laser beam through the transparent glass slide at a given depth within the given medium and a transmitted phase reference laser beam and a transmitted sensitive probe laser beam undergoing the slight phase changes are generated.
