“…These radicals can damage the cell membrane leading to leakage of cytoplasm and cell death [28]. In turn, Woskowicz et al showed that the strong bactericidal properties of the AgO coated by magnetron sputtering on polymer surface can be associated with low durability of the coating and the release of ions into the environment [22].…”

“…The literature presents a number of membrane modifications consisting in the formation of a coating on the surface in order to obtain resistance to organic and biological pollution [13][14][15][16][17][18][19][20]. Recently, new trends have arisen around the development and use of plasma surface engineering techniques for the modification and shaping functional properties of polymeric materials [21][22][23]. Magnetron sputtering (MS-PVD) technology is one of the plasma methods of surface engineering used to create a thin functional coating on the membrane surface to impart bactericidal properties.…”

Microfiltration (MF) membranes have been widely used for the separation and concentration of various components in food processing, biotechnology and wastewater treatment. The deposition of components from the feed solution and accumulation of bacteria on the surface and in the membrane matrix greatly reduce the effectiveness of MF. This is due to a decrease in the separation efficiency of the membrane, which contributes to a significant increase in operating costs and the cost of exploitative parts. In recent years, significant interest has arisen in the field of membrane modifications to make their surfaces resistant to the deposition of components from the feed solution and the accumulation of bacteria. The aim of this work was to develop appropriate process parameters for the plasma surface deposition of silver oxide (AgO) on MF polyamide membranes, which enables the fabrication of filtration materials with high permeability and antibacterial properties.

Improved protection of urinary stents against infections is a significant current challenge because of the increasing microbial resistance to the conventional antibiotics and negative issues for the patients. Formation of crystalline biofilms of pathogenic microbial cells is the leading cause of urinary stent associated infections. A lot of approaches, antimicrobial agents and techniques are under a study to mitigate the problem by creation of contact killing; releasing or low adhesive surfaces do not allow attachment of microbial cells. The plasma treatment has a number of advantages that make it preferable in many strategies for the development of antimicrobial biomaterials. The control over the plasma processing parameters allows control over the surface chemistry, charge, structure, morphology, hydrophilic/hydrophobic balance, etc. Due to a variety of biomaterials and bacteria, causing urinary tract infections, plasma assisted antibacterial strategies need in tailoring to each specific surface. Plasma treatment of polymers under corresponding operation conditions allows deposition of contact killing, releasing (including controlled release) or low-adhesive antimicrobial coatings, as well as polymer surface functionalization and durable immobilization of antimicrobial molecules. Most of the plasma technologies are developed in laboratory and the surface engineered biomaterials are tested in vitro.

“…An average value of the contact angle between the sample surfaces and a minimum of two drops was measured using the sessile drop method. The static contact angle was obtained analyzing the captured images using the Tangent Method 1 algorithm [11]. The wettability of the surface with a polar (H2O) and non-polar (diiodomethane) solvent was analyzed.…”

This paper present the issue of plasma treatment of the surface of polypropylene (PP) using AgO+CuO coatings in order to antimicrobial activity. The analyzed coatings were deposited using High Power Impulse Magnetron Sputtering (HPIMS). This method is characterized by high power density, high ionization and high plasma density, which enables the production of high-quality multi-component coatings. All CuO+AgO coatings, formed on the polypropylene (PP) surface by MS-PVD magnetron sputtering with various parameters, were tested in terms of morphology, chemical composition, mechanical properties and antibacterial properties. The conducted analysis showed a significant influence of the chemical composition on the structure, density and mechanical properties of the obtained coatings. The analysis of the continuity of structure different CuO+AgO coatings showed that its depending on chemical composition. Furthermore, different growth mechanism of the coatings are observed. It was also found that plasma treatment of polypropylene (PP) with CuO+AgO layers allows to provide good antimicrobial properties.
