Abstract:
The invention relates to a method for analysing an interaction between a first molecule and a second molecule bonded to a particle, including the following steps: contacting the first molecule with the second molecule bonded to the particle under conditions enabling the interaction thereof; applying a predetermined liquid flow to the particle bonded to the second molecule; observing a movement of the particle bonded to the second molecule caused by the applied flow; analysing the interaction according to the movement observed and the applied flow, the particle having a greater hydrodynamic resistance than the first and/or second molecule, and a mass Péclet number of greater than 1. The invention also relates to a device for analysing an interaction between a first molecule and at least one second molecule, as well as to the use of the method or of the device in screening a candidate molecule for developing a drug.
Abstract:
The synthesis of electronic components incorporating nanometric filament structures comprises: (a) depositing, on a nanoporous membrane (3), a metallic catalyst (7) adapted to penetrate into at least a part of the pores (8) of the membrane; (b) producing a growth of nanometric filament structures on the catalyst in at least a part of the pores of the membrane; (c) the membrane is prepared in a manner adapted in order that the walls of the pores incorporate a monocrystalline zone and with epitaxy of at least partially the catalyst on this monocrystalline zone. An independent claim is also included for an electronic component produced by this method.
Abstract:
La présente invention se rapporte à un système laser femto seconde comprenant : - une pluralité d'amplificateur laser (3) à fibre optique émettant chacune un faisceau laser impulsionnel intermédiaire selon une longueur d'onde commune; - des moyens de concentration (7) de l'ensemble des faisceaux laser impulsionnels intermédiaires transformant l'ensemble des faisceaux laser impulsionnels intermédiaires en un unique faisceau laser impulsionnel final; et - des moyens de synchronisation (11) de la pluralité des amplificateurs adaptés pour gérer les décalages de front d'onde des faisceaux laser intermédiaires, caractérisé en ce que la pluralité des amplificateurs laser (3) sont positionnées de telle sorte que les faisceaux laser impulsionnels intermédiaires se propagent le long des rayons d'une sphère.
