Publication number: 20120021554Abstract: A method of formation of nanowires at a surface of a substrate attached to a solid immersion lens. The method includes formation of a catalyst element at the surface of the substrate and growth of nanowires from the catalyst element formed at the surface of the substrate. The catalyst element is a metal nanoparticle and the formation of the catalyst element at the surface of the substrate deposits the metal nanoparticle using a light beam focused by the solid immersion lens at the surface of the substrate.Type: ApplicationFiled: January 28, 2010Publication date: January 26, 2012Applicant: Commissariat A L'Energie Atomique et aux Ene AltInventors: Delphine Neel, Pierre Ferret, Stéphane Getin

Patent number: 7521255Abstract: A method for controlling directly and in real time positioning of a biological element on a zone of a support, in which the biological element is labeled with a tracer that emits a light radiation and the zone of the support is located in a layer of a material capable of trapping the light radiation. The biological element is positioned on the zone of the support. The intensity of the light radiation trapped in the layer is measured. The positioning of the biological element is determined by comparing the intensity thus measured with at least one reference value. The above operations can be carried out successively or simultaneously. A device can apply the method to the positioning of one or more biological elements on one or more zones of a support.Type: GrantFiled: February 23, 2005Date of Patent: April 21, 2009Assignee: Commissariat a l'Energie AtomiqueInventors: Nathalie Picollet-D'Hahan, Patrick Chaton, Stephane Getin
