Abstract: A method for altering adhesion properties of a surface of a substrate by a coating, comprising the steps of: a) ionizing a plasma gas at low temperature and at atmospheric pressure, thereby creating a plasma with a plasma temperature of at most 50° C.; b) introducing a precursor into a plasma gas afterglow of the plasma; c) subjecting the surface of the substrate to the plasma including the precursor, thereby forming a coating onto the surface. The plasma gas is essentially completely comprised of inert gas. The coating alters the adhesion properties of the surface.

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.

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 said plasma; c) exposing the surface to said plasma comprising said precursor, thereby forming a coating onto the surface. The precursors include a biological pathogen transfer inhibiting compound.
