摘要:
The invention relates to a method for precipitating mono or multiple layers of organophosphoric acids of the general formula I (A) Y—B—OPO3H2 (IA) or of organophosphonic acids of the general formula I (B) Y—B—PO3H2 (IB) and the salts thereof, wherein B is an alkyl, alkenyl, alkinyl, aryl, aralkyl, hetaryl or hetarylalkyl residue and Y is hydrogen or a functional group from the hydroxy, carboxy, amino, optionally low-alkyl-substituted mono or dialkylamino series, thiol, or a negative acid group from the ester, phosphate, phosphonate, sulfate, sulfonate, maleimide, succinimydyl, epoxy, acrylate series, wherein a biological, biochemical or synthetic indicator element may be coupled to B or Y by addition or substitution reaction, wherein compounds may also be added conferring the substrate surface a resistance to protein adsorption and/or to cell adhesion and in the B chain may optionally be comprised one or more ethylene oxide groups, rather than one or more —CH2- groups. According to the invention, said precipitation occurs on substrate surfaces of pure or mixed oxides, nitrides or carbides of metals and semiconductors, comprising the use of water-soluble salts of a compound of formula (IA) or (IB) for the treatment of these surfaces, in particular as surfaces of sensor platforms, implants and medical accessory devices. The invention also relates to the use thereof as part of coated sensor platforms, implants and medical accessory devices in addition to new organophosphoric acids and organophosphonic acids themselves. The optionally substituted compounds of formulae (IA) and (IB) wherein the B and Y groups have the above-mentioned designations, i.e. optionally substituted alkyl, alkenyl, alkinyl, aryl, aralkyl, hetaryl or hetaryl, are hereinafter referred to as organophosphoric acids and organophosphonic acids.

摘要:
A one- or two-dimensional arrangement of flow cells is provided, as part of an array of sample compartments, with at least one inlet and outlet for each sample compartment, formed by a base plate and a body, with an arrangement of spatial recesses corresponding to the (geometrical) arrangement of the sample compartments, combined with the base plate. The arrangement allows for supplying to or removing from the sample compartments, which can be arranged at a high quantity on a small base area, even very small amounts of samples or reagents. An arrangement of one or more sample compartments includes a base plate and a body combined with the base plate in such a way that one or more recesses for generation of one or more flow cells fluidically sealed against one another, each with at least one inlet and one outlet, are formed between the base plate and the body, wherein at least one outlet of each flow cell is joined with a reservoir fluidically connected with the flow cell, the reservoir being operable to receive liquid exiting the flow cell, besides methods for its manufacturing and their use.

A device includes a planar optical waveguide, as part of a sensor platform, and, connected to the platform directly or by means of a sealing medium, a sealing layer. The sealing layer forms either directly or by means of a sealing medium a tightly sealing layer. The sealing layer includes a multitude of recesses at least open towards the sensor platform, which form a corresponding multitude of sample compartments in a 2-dimensional arrangement. Each of the sample compartments has different biological or biochemical recognition elements, for the specific recognition and binding of different analytes, immobilized in five or more discrete measurement areas, wherein the measurement areas are in optical interaction with excitation light emanating from the optical waveguide, as part of the sensor platform which forms a demarcation of the sample compartments, and wherein the sample compartments are operable to be cleared from received sample or reagent solutions and to then receive, optionally without washing steps, further sample or reagent solutions, which are supplied to the same sample compartments.
