Title (EN) A METHOD FOR DETERMINING A HYDRODYNAMIC SIZE OF AN OBJECT
(FR) PROCÉDÉ POUR DÉTERMINER UNE TAILLE HYDRODYNAMIQUE D'UN OBJET
Abstract:
(EN) The disclosure relates to a method for determining a hydrodynamic size of an object, such as a nano-sized object, said method comprising the steps of: - providing a fluid interface, - linking said object to said fluid interface thereby providing a linked object, whereby the movement of said linked object is restricted by virtue of being linked to said fluid interface, - providing and determining a hydrodynamic shear force that acts on said linked object, - tracking the movement of said linked object, and - calculating the hydrodynamic size of the object using the Einstein-Smoluchowski relation.
(FR) L'invention concerne un procédé pour déterminer une taille hydrodynamique d'un objet, tel qu'un objet de taille nanométrique, ledit procédé comprenant les étapes consistant : - à fournir une interface fluidique, - à relier ledit objet à ladite interface de fluide pour fournir ainsi un objet lié, ce par quoi le mouvement dudit objet lié est restreint du fait d'être lié à ladite interface de fluide, - à fournir et à déterminer une force de cisaillement hydrodynamique qui agit sur ledit objet lié, - à suivre le mouvement dudit objet lié, et - à calculer la taille hydrodynamique de l'objet à l'aide de la relation Einstein-Smoluchowski.
