“…A possible explanation of the cracks formation can be ascribed to the higher discharge temperature when water droplets (and water vapor) were introduced in the discharge [ 42 ] indeed thermal stress of the deposited coatings and treated substrates could have induced crack and defect production [ 43 ]. Even if defects of plasma coating deposition are usually undesired [ 44 , 45 ] Nikiforov et al [ 46 , 47 ] reported on the key role of cracks for the delivery of silver ions from nanostructured films deposited on non-woven fabrics.…”

In industrialized countries, health care associated infections, the fourth leading cause of disease, are a major health issue. At least half of all cases of nosocomial infections are associated with medical devices. Antibacterial coatings arise as an important approach to restrict the nosocomial infection rate without side effects and the development of antibiotic resistance. Beside nosocomial infections, clot formation affects cardiovascular medical devices and central venous catheters implants. In order to reduce and prevent such infection, we develop a plasma-assisted process for the deposition of nanostructured functional coatings on flat substrates and mini catheters. Silver nanoparticles (Ag NPs) are synthesized exploiting in-flight plasma-droplet reactions and are embedded in an organic coating deposited through hexamethyldisiloxane (HMDSO) plasma assisted polymerization. Coating stability upon liquid immersion and ethylene oxide (EtO) sterilization is assessed through chemical and morphological analysis carried out by means of Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). In the perspective of future clinical application, an in vitro analysis of anti-biofilm effect has been done. Moreover, we employed a murine model of catheter-associated infection which further highlighted the performance of Ag nanostructured films in counteract biofilm formation. The anti-clot performances coupled by haemo- and cytocompatibility assays have also been performed.

“…After detailed and careful optimization of the process parameters (monomer and crosslinker content, plasma treatment time, discharge power), hydrophobic coatings with good washing durability were obtained. Nikiforov et al 156 used an APP deposition process of HMDSO to deposit a thin organosilicon film on PET fabrics in order to enhance subsequent deposition and adhesion of silver, copper, and zinc oxide nanoparticles (NPs). Initial deposition of organosilicon film using N 2 with a small amount of O 2 onto the PET surface was followed by immersion in a dispersion of NPs in ethanol.…”

This paper gives an overview of atmospheric pressure plasma types used in the textile industry and recent developments in plasma treatments of textiles. It investigates the topic of the influence of atmospheric pressure plasma treatment on the surface properties of materials made from natural and synthetic fibers. Through plasma induced physical and chemical reactions occurring in the textile surface layer, significant modifications in micromorphology and reactivity can be achieved. In addition to cleaning, etching, and activation, great efforts have been made in the development of plasma polymerization processes under atmospheric pressure. Utilization of atmospheric pressure plasma technology in the textile industry offers a new perspective on surface modification and functionalization. This paper gives a summary of textile properties achieved using plasma and the underlying processes based on relevant findings obtained from prominent research.

“…Fahmy et al and Cruz et al attached silver NPs on a surface by using plasma polymerization of allyl alcohol and polymethylmethacrylate respectively, followed by incorporation of silver NPs on top of the plasma polymerized layer [38,39]. The reversed order process, deposition of a thin layer of plasma on top of silver NPs to improve adhesion, has not been extensively explored [40]. This is probably because direct contact from silver NPs, which not probable from below a conformal coating, is usually considered to be a requirement for antibacterial effect, as demonstrated in literature [41].…”

Effect of plasma coating on antibacterial activity of silver nanoparticles

et al. 2019

Silver nanoparticles (NPs) are known to provide antimicrobial properties for surfaces.However, there are environmental concerns due to reports of toxicity after exposure to the environment during or after end-use. Immobilizing silver NPs to the surface of substrates could ensure that particles are readily available for antibacterial activity with limited environmental exposure. A plasma coating on top of silver NPs could improve the adhesion of NPs to a substrate, but it could also impede the release of silver NPs completely. Furthermore, silver has been shown to require direct contact to demonstrate antibacterial activity. This study demonstrates immobilization of silver NPs with plasma coating onto a surface while maintaining its antibacterial properties. Silver NPs are simultaneously synthesized and deposited onto a surface with liquid flame spray aerosol technique followed by hexamethyldisiloxane plasma coating to immobilize the NPs. Atomic force microscope scratch testing is used to demonstrate improved nanoparticle adhesion. Antibacterial activity against gram-negative Escherichia coli is maintained even for plasma coating thicknesses of 195 nm. NP adhesion to the surface is significantly improved. Gram-positive Staphylococcus aureus was found be resistant to all the plasma-coated samples. The results show promise of using plasma coating technology for limiting NP exposure to environment. Highlights: Roll-to-roll synthesis of silver nanoparticles using Liquid flame spray  Plasma coating for improved nanoparticle adhesion to substrate  Antibacterial properties of silver nanoparticles across plasma layer  Limited environmental exposure of silver nanoparticle
