  • Publication number: 20160274107
    Abstract: The present invention is related to a method of studying (i) binding reactions, (ii) dissociation reactions, (iii) competitive binding reactions, or (iv) association reactions between two or more molecules in a biological sample by means of super-resolution imaging, in which method the reaction as such causes an event that forms the basis for the identification and localization-based super-resolution microscopy of the reaction (FIG. 1a).

  • Patent number: 7889343
    Abstract: Method and system for optical detection of nano-objects in a refracting medium. A nano-object (n_oi) and the refractive medium are illuminated (A) with a periodically amplitude modulated coherent electromagnetic heating wave (HB(?)), to generate a specified temperature and refractive index profile in the vicinity of the nano-object, and with a coherent electromagnetic probe wave (PB) to generate an emerging probe wave (EPB(?)) having at least one intensity component amplitude modulated by a beat at the modulation frequency of the coherent heating wave. The intensity component amplitude modulated by a beat is detected (C) in the emerging wave (EPB(?)), to distinguish and represent this nano-object in the refractive medium. The invention is useful in the detection of nano-objects in an industrial, physiological or intracellular medium.

  • Patent number: 6756591
    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.
