“…using an asymmetric reactor design. [71] In order to demonstrate some of the characteristics determining protein adsorption, a number of different surfaces have been constructed in an attempt to correlate the type and density of functional groups with protein adsorption. The proteins studied were fibrinogen, bovine serum albumin (BSA), and immunoglobulin (IgG) on plasmapolymerized coatings of amine-, acid-, and ether-functionalized precursors.…”

This review aims to provide a summary of some of the challenges in correlating surface science and biology, with particular emphasis on areas where plasma polymerization has and will play an important role as a method to synthesize reproducible and well-defined surfaces. Since the range of possible applications of plasma polymer films in biomaterial applications is immense, this paper will focus on processes to develop various surface morphologies and chemical structures for the immobilization of proteins and cells. Functional, plasma-polymerized films are discussed as biosensitive interfaces that may ultimately be part of a multilayer system that aims at connecting inorganic/metallic transducers with biologically reactive surfaces. These topics will be reviewed with some experimental results taken from the authors' own work. Specific aspects such as adhesion improvement and solvent effects are also discussed.

“…PEO-like coatings were plasma-deposited at LP [101] at 60 W power (high fragmentation conditions), 20 sccm Ar, 0.25 sccm DEGDME, 50 mTorr for 15 min. XPS show high cross-linking of the coating, attested by the low amount of -CH 2 CH 2 O- moieties (i.e., low PEO-character, grey peak in Figure 7), and by the presence of -COOH groups.…”

Non-Equilibrium Plasma Processing for the Preparation of Antibacterial Surfaces

Non-equilibrium plasmas offer several strategies for developing antibacterial surfaces that are able to repel and/or to kill bacteria. Due to the variety of devices, implants, and materials in general, as well as of bacteria and applications, plasma assisted antibacterial strategies need to be tailored to each specific surface. Nano-composite coatings containing inorganic (metals and metal oxides) or organic (drugs and biomolecules) compounds can be deposited in one step, and used as drug delivery systems. On the other hand, functional coatings can be plasma-deposited and used to bind antibacterial molecules, for synthesizing surfaces with long lasting antibacterial activity. In addition, non-fouling coatings can be produced to inhibit the adhesion of bacteria and reduce the formation of biofilm. This paper reviews plasma-based strategies aimed to reduce bacterial attachment and proliferation on biomedical materials and devices, but also onto materials used in other fields. Most of the activities described have been developed in the lab of the authors.

“…It has been demonstrated earlier that PEO-like films and Ag NPs can be deposited at the same time using dedicated equipment and under careful control of the deposition conditions to fabricate a PEO/Ag nanocomposite [211]. On the other hand, it is also advantageous to fabricate Ag NP/PEO-like coatings by using a strategy that allows adjusting the nature of the coating and to synthesize and deposit the Ag NPs independently from each other.…”
