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 method for plasma coating a compressible structure, includes the steps of: compressing the compressible structure thereby removing air from the compressible structure; and coating the compressed structure according to the following steps: a) ionizing a plasma gas at a temperature of 150° C. or lower, and at about atmospheric pressure, thereby creating a plasma; b) introducing a precursor into said plasma, thereby obtaining a precursor-comprising plasma; c) exposing the compressed structure to said precursor-comprising plasma, thereby forming a coating onto surfaces of the structure.

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.

Abstract: A method for plasma coating an object includes an object profile, having the steps of: a) manufacturing a replaceable shield comprising a jet inlet, a nozzle outlet and a sidewall extending from the jet inlet to the nozzle outlet, wherein the nozzle outlet includes an edge essentially congruent to at least part of the object profile; b) detachably attaching the replaceable shield to a jet outlet of a plasma jet generator; c) placing the object at the nozzle outlet such that the object profile fits closely to the nozzle outlet edge; d) 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.
