    Abstract: A method for depositing a coating on a substrate is disclosed. A first precursor comprising fluoro-acrylate monomers, fluoro-alkyl acrylate monomers, fluoro-methacrylate monomers, fluoro-alkyl methacrylate monomers, fluoro-silane monomers, or a combination or derivates thereof is provided. A second precursor comprising linear siloxanes, silane monomers, cyclosiloxanes, cyclosilane monomers, or a combination or derivates thereof is provided. The first and second precursors are co-injected in a treatment region. An atmospheric or reduced pressure plasma discharge is created in said treatment region. The substrate coating comprises alternated multi-stacked nanostructures and is formed by copolymerization of the first and second precursors.

    Abstract: A plasma coating an object has an object profile, and includes the steps of: providing a replaceable shield including a jet inlet, a nozzle outlet and a sidewall extending from the jet inlet to the nozzle outlet; detachably attaching the replaceable shield to a jet outlet of a plasma jet generator; placing the object at the nozzle outlet such that the object profile fits closely to the nozzle outlet edge to within a distance of at least 0.1 mm and at most 5 mm; plasma coating the object with a low-temperature, oxygen-free plasma at an operating pressure which is higher than the atmospheric pressure by providing a plasma jet in the shield via the plasma jet generator and injecting coating precursors in the plasma jet in the shield; identifying the provided shield prior to providing the plasma jet.

    Abstract: A two-step method is provided for the immobilization of a biomolecule through a linking molecule on a sample surface of a substrate by generating and maintaining a non-thermal atmospheric pressure plasma at a temperature between room temperature and 60° C. The preferred plasma temperature is room temperature. The method comprises of a first step and second step, which are sequentially carried out. In the first step of the method, the linking molecule is deposited onto the sample surface through exposing the sample surface to a first plasma jet and the linking molecule, generating a linking layer onto the sample surface. In a second sequential step of the method, the biomolecule is deposited onto the linking layer through exposing the linking layer to a second plasma jet and the biomolecule.
