“…Plasmas can also be categorized in terms of the surface properties that result from the process of polymerization. One outcome of plasma processing can be the insertion of various chemically reactive surface groups, which can then be used to perform conventional chemical reactions for the surface attachment of desired molecules, such as specific biologically active entities such as proteins or aptamers, that could otherwise not be attached onto the surfaces of solid materials via aqueous chemical reactions. Another aim of plasma processing can be the fabrication of hydrophilic, usually hydrated surfaces and coatings that are chemically inert under the intended usage conditions; such passive hydrated surfaces are of interest for various biomedical and biotechnology applications.…”

This review focuses on low-pressure plasma modification methods to produce hydrophobic coatings and surface modifications on biomaterials. Plasma-deposited fluoropolymer, siloxane, and diamond-like carbon (DLC) coatings are reviewed in terms of process developments, monomers used, stability and aging properties, and their behavior in adsorption of proteins, cell attachment, and bacterial adhesion. These hydrophobic coatings are stable with correct selection of monomers and process conditions, but the plasma polymerized siloxane and fluorocarbons have been mainly applied in biochip and test kits rather than in blood-contact applications. Similarly, the surface characteristics and interfacial bonding of DLC coatings play a crucial role in their successful implementation.

“…The effectiveness of plasma modification highly depends on substrate gas used for the treatment, reactor design, or the type of biomaterial subjected to the modification. In engineering of biomaterials, plasma (recently special attention has been paid to atmospheric pressure plasma) combined with argon, oxygen, air, amonia, or nitrogen gas is most often used for surface modifications of primarily polymeric materials [68,69,70,71]. Kostov et al [72] modified polyethyleneterephthalate, polyethylene (PE), and polypropylene with cold atmospheric plasma jet using argon gas and obtained polymers with increased roughness and wettability.…”

The aim of engineering of biomaterials is to fabricate implantable biocompatible scaffold that would accelerate regeneration of the tissue and ideally protect the wound against biodevice-related infections, which may cause prolonged inflammation and biomaterial failure. To obtain antimicrobial and highly biocompatible scaffolds promoting cell adhesion and growth, materials scientists are still searching for novel modifications of biomaterials. This review presents current trends in the field of engineering of biomaterials concerning application of various modifications and biophysical stimulation of scaffolds to obtain implants allowing for fast regeneration process of bone and cartilage as well as providing long-lasting antimicrobial protection at the site of injury. The article describes metal ion and plasma modifications of biomaterials as well as post-surgery external stimulations of implants with ultrasound and magnetic field, providing accelerated regeneration process. Finally, the review summarizes recent findings concerning the use of piezoelectric biomaterials in regenerative medicine.

The ability of non-equilibrium plasmas to modify surfaces has been known for many years. And a promising way to perform surface modifications without altering the bulk properties is plasma polymerization since this technique is versatile and can be applied to a wide range of materials. Plasma polymer films usually show good biocompatibility when compared to classical biomaterials. The possible biomedical use of plasma polymers motivates the study of their behavior during storage and in aqueous environment. Therefore, it is of major importance to understand the change of properties of these plasma polymers over time and when in contact with certain fluids. Recently, plasma polymer gradients (surfaces that display a change in at least one physicochemical property over distance) have attracted significant attention from the biomedical filed where the interaction of cells with a material surface is of major interest. This chapter discusses biomaterial functionalization via plasma polymerization focusing on their use in the biomedical field as well as their aging and stability behaviors. Plasma polymer gradients as valuable tools to investigate cell-surface interactions will also be reviewed.
