  • Publication number: 20230416921
    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.

  • Publication number: 20230201870
    Abstract: A method for providing a bio-active layer on a surface, includes the steps of: a) ionizing a plasma gas at low temperature of 150° C. or lower, and at about atmospheric pressure, thereby creating a plasma; b) introducing a precursor into the plasma; c) exposing the surface to the plasma comprising the precursor, thereby forming a coating onto the surface. The plasma gas is ionized by means of electrodes, wherein the plasma gas is ionized by the electrodes with a power of at most 10 Watt per cm2 of the electrode surface. The bio-active layer is an antibiofouling layer, an antibacterial layer, an antiviral layer and/or a microbial collecting layer, such that the plasma gas includes inert gas for at least 99% by volume. The inert gas is a non-noble gas.

  • Publication number: 20220001419
    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.
