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.

The precursors include a biological pathogen transfer inhibiting compound.

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 filter device for filtering nano particles conveyed in a fluid in order to determine an exposure of the filter device to nano particles includes a support element having a top surface, a bottom surface, a lateral surface, and at least one fluid duct having a fluid inlet and a fluid outlet. The top surface and the bottom surface extend substantially parallel to each other. The filter device further includes at least one filter element with a collection surface on which the nano particles are to be deposited. The at least one filter element is arranged in the at least one fluid duct for collecting the nano particles conveyed in the fluid. The collection surface of the at least one filter element is oriented parallel to at least one of the top surface and the bottom surface.
