Abstract: The invention relates to several embodiments of equipment for coating substrates for detecting one or more analytes by way of an affinity assay method, comprising: a receptacle receiving a liquid to be atomized (“liquid receptacle”) with substances (compounds) to be deposited onto at least one surface of said substrates and an atomized volume produced by the liquid in the operating state; an actuator for triggering the atomization process and; a fixture for receiving and storing the substrates during the coating process. The invention is characterized in that the substrates are not in contact with the surface of the liquid to be atomized. The invention also relates to several embodiments of methods for coating substrates with coupler and/or passivation layers for use in the detection of one or more analytes by way of an affinity assay method.

Abstract: The invention relates to a surface for the immobilization of one or several first nucleic acids as recognition elements (“immobilization surface”), for the production of a recognition surface for the detection of one or several second nucleic acids in one or more samples which are brought into contact with the recognition surface, the first nucleic acids being applied to a layer of the graft copolymer poly(L-lysine)-g-poly(ethyleneglycol) (PLL-g-PEG) as surface for immobilization, characterized in that the grafting ratio g, in other words the ratio between the number of lysine units and the number of polyethylene glycol side chains (“PEG” side chains) has an average value between 7 and 13.
