    摘要: A collection of colloidal particles in the form of one or several chains, in which the chains are generated in an irreversible manner and have at least one recognition site for a species, the site being different from sites implicated in the linear organisation of the particles. The invention further relates to a method for production of the collection, particularly for detection and/or dosage of at least one species in a fluid and a surface element functionalised by a collection of colloidal chains and a hybridisation network including such a surface element.

    摘要: The invention concerns a method for separating particles or molecules whereby these particles or molecules are introduced in a separating medium and a moving force is applied to them in said medium. The method is characterised in that the separating medium is a ferrofluid, i.e. a colloidal suspension of magnetic particles and a magnetic field is applied to this ferrofluid generating therein at least an alternation of a zone rich in magnetic particles and a zone poor in magnetic particles, part at least of the region of the ferrofluid in which this alternation is generated is passed through by the particles or molecules to be separated during their migration.

    摘要: In order to separate, within a fluid (1), certain particles (2) contained therein, this fluid is arranged in a corridor (C) partly defined by two faces which are close together and substantially parallel to each other and to the direction of separation E and an exciting field is simultaneously applied to the entire volume of fluid contained in this corridor, according to a direction having at least one component perpendicular to the direction E, which exciting field varies along the said direction in a curve consisting of a regular sequence of mutually identical asymmetric patterns, the mean of this field, taken at each instant along the direction E, being zero, and means are provided for repetitively varying the effect of the exciting field on the particles. The substantially parallel faces may be electrodes between which a potential difference source is connected for producing an electric field thereby exciting particles in the corridor (C). At least one of the electrodes has a corrugated surface with a sequence of asymmetric grooves transverse to the separation direction.
