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.

Abstract: A three-dimensional (3D) cell culture system comprising: a solid porous polymeric support, preferably comprising a biocompatible polymer; a first type of cells bound to the solid porous polymeric support; and a biocompatible hydrogel comprising a second type of cells, wherein biocompatible hydrogel is in physical contact with the solid porous polymeric support, is described. Methods for preparing this 3D cell culture system, as well as uses of this system for example for anticancer drug screening, are also described.

Abstract: The present invention is related to a method for protecting a metal substrate against corrosion comprising the step of: —generating a plasma in a gaseous medium by means of a plasma device; —placing the substrate in contact with the plasma, or in a post-plasma area of said plasma; —introducing in said plasma or in said post-plasma area a corrosion inhibitor along with an organic precursor, thereby depositing a barrier layer comprising the corrosion inhibitor, the deposited layer protecting the metal substrate against corrosion.
