Abstract: A polysaccharide coated carrier having a coating of at least two successive layers of polysaccharide. The first polysaccharide layer spontaneously associates with a second polysaccharide layer and, optionally, the carrier. Each successive layer of polysaccharide spontaneously associates with a preceding layer. Spontaneous association occurs due to the presence of oppositely charged functional groups on each layer of polysaccharide or due to a spontaneous reaction between the functional groups the layers. The carrier may be any surface such as a tube, microtitration plate, bead, particle or the like and is suitable for use in diagnostic or therapeutic methods.

Abstract: The invention relates to a method and to a diagnostic agent for detecting hemostasis disturbances, wherein, as a consequence of blood platelet aggregation, clot formation and/or clot dissolution, substances are brought to a distance from each other which permits or prevents an interaction, in particular an energy transfer, between the substances, and the extent of the interaction is measured.

Abstract: The present invention relates to a piezoelectric sensor for use in diagnostic and analytic processes, in particular for the immunochemical detection of diagnostically relevant specific binding partners.

Abstract: The present invention relates to a method for carrying out immunochemical reactions and to regenerable solid phases which can be used for this purpose. When use is made of precious metals, preferably gold, as the solid phase, and also of certain reducing agents or oxidizing agents, such as, for example, sodium borohydride and tetrabutylammonium hydroxide, with or without the addition of detergents, the solid phase can be employed repeatedly, following regeneration.
