Abstract: A biosensor for detecting an antigen using an antigen/antibody coupling includes: a silicon substrate, at least one interdigital electrode pair structure that is located on the silicon substrate, the electrode pair being interspaced at a maximum distance of 1.0 ?m; a counter-electrode on the silicon substrate; a reference electrode; a first layer of protein, covering at least the interdigital electrode structure; a selective second protein layer applied to the first layer and containing a capture antibody selected specifically with respect to the antigen of interest and to which the antigen can be coupled. A sensor signal can be read on the interdigital electrode structure, if the antigen is coupled to the capture antibody by way of a sample to be analyzed that comes into contact with the biosensor and a redox reactive molecule is enzymatically released on the sensor surface by an enzyme-marked detection antibody likewise coupled to the antigen.

Abstract: A process for finishing absorbent material which comprises it being (A) hydrophilicized in a first step (B) treated in a subsequent step with at least one aqueous liquor comprising (a) at least one organic polymer, (b) at least one organic or inorganic solid in particulate form other than (a), and (c) at least one emulsifier.

Abstract: A biosensor is for detecting an allergen-specific immunoglobulin E (IgE) via antigen/antibody coupling. The biosensor includes a silicon substrate and at least one interdigital electrode pair structure applied to the silicon substrate with a gap between the electrode pairs of a maximum of 1.0 ?m. A counter electrode is further applied to the silicon substrate. The biosensor also includes a reference electrode. Additionally, coatings are included on the biosensor. A first coat is made from protein coating at least the interdigital electrode structure; a selective second coat is made from protein applied over the first coat, the second coat containing a selected captor antibody; and a third coat is applied over the first coat, which contains the allergen which can couple to the captor antibody.
