“…Among them, atmospheric pressure plasma spraying (APPS) stands as a very versatile and easily upscalable process. It allows to functionalize a vast range of substrates (glass, metal, polymers) for different applications, like enhancement of tribological properties [30][31][32], thermal [33],corrosion protection [34,35] or adhesion promotion [36] to cite a few. Particularly, cell and proteinrepellent poly(ethylene glycol)-based hydrophilic surfaces were obtained through atmospheric pressure plasma spraying [37,38].…”

This work aims at studying the impact of silane-based coatings, generated by atmospheric pressure plasma spraying (APPS) of a liquid precursor (hexamethydisiloxane -HMDSO), on dairy antifouling and antibacterial properties of food-grade 316L stainless steel. The influence of the manufacturing parameters (precursor flow rate, nozzle-to-substrate distance and scanning speed) on the coatings properties was investigated using a wide range of characterization techniques (drop shape analysis, X-Ray Mappings, Scanning Electron Microscopy, Fourier-Transformed Infrared Spectroscopy, Atomic Force Microscopy). Coating's roughness in particular was shown to strongly increase when precursor flow rate increases. A pilot pasteurizer, fed with a model foulant solution (whey protein and calcium), allowed performing two consecutive industrial-like isothermal dairy fouling tests, revealing the promising anti-fouling properties of the HMDSO-coated steel. A fouling reduction of up to 90% compared to bare stainless steel was achieved after first cycle for all samples. The second fouling run allowed to select the best-performing sample, which kept the same antifouling properties as in the first test.Its mechanism of action was investigated, which revealed that a nanostructured, Si-O-Si rich surface was efficient to prevent isothermal dairy fouling. The adhesion of the pathogenic bacterium Staphylococcus aureus also proved to be impacted by this plasma coating, with a significant decrease of adhered cells (-30% compared to native stainless steel).

“…[2,39] Silicone oil-derived coating present a uniform coverage over the seed surface, covering its microtubules as well as presenting a smooth and homogeneous appearance, similar to the one reported for other organosilicon coatings deposited using atmospheric plasma. [23,40] No pores or other surface heterogeneities can be observed. The film thickness can be observed from the longitudinal section, which is approximately 7 μm.…”

Vegetable ivory obtained from the endosperm of jarina seeds (Phytelephas macrocarpa), native to the Amazon region, has been regarded as a sustainable alternative to elephant ivory; however, it is vulnerable to biodegradation due to its mannan polysaccharide composition. In this study, vegetable ivory was coated by atmospheric air plasma jet activation of silicone and copaiba oils. Stable, smooth, and crosslinked micrometric coatings were formed after 80 s of plasma activation. Water contact angle results show that hydrophobicity was enhanced without detrimental effects on the surface reflectance. The best antibacterial performance against Staphylococcus aureus and Escherichia coli was obtained for a 1:1 mixture of both oils due to the synergetic action of silicone hydrophobicity and copaiba bioactivity.

“…As an alternative to above mentioned chemical approaches, the plasma enhanced chemical vapor deposition of thin functional coatings can be employed. It has already been successfully applied to a preparation of plasma polymers containing carboxyl [16][17][18], amine [19] or anhydride groups [20], deposition of superhydrophobic [21,22] and hard diamond-like carbon [23] thin films. It is known that the essential chemical and thickness stability of the plasma layers can be achieved by tuning the plasma parameters [24,25].…”

Biosensors have been extensively developed and applied for biomedical and environmental studies. Although there are many different types of biosensing techniques, immobilization of the biorecognition biomolecules onto the sensor surface is always required. Cyclopropylamine pulsed plasma polymerization in radio frequency (RF) capacitive discharges was employed to deposit amine thin films on the gold electrode of quartz crystal microbalance (QCM) biosensors and the monoclonal antibody AL-01, specific to human serum albumin (HSA), was immobilized onto the plasma polymer surface. Two different amine plasma polymers were studied. They had a similar amount of primary amine groups, 1.3-1.5 at.%, as determined by chemical derivatization but their stability in water was different. The 1 st type, deposited at the floating potential and 120 Pa, exhibited 16 % thickness loss after 24 hours in water whereas the 2 nd type deposited at RF electrode and 50 Pa was completely stable (2% thickness loss). Glutaraldehyde (GA) coupling of AL-01 was employed for both types of the amine films and the performance of QCM immunosensors was evaluated by the immunoassay flow test. A high-stability of the frequency signal was obtained in both the cases but the 2 nd type of the film provided low response to HSA. It was explained by its highly cross-linked structure and steric hindrance of active sites. Three different antibody immobilization methods were explored for the 1 st type of the film. Stable baseline, selective and high response were recorded for GA and sulfo-SMCC methods. The results confirmed that the presented methodologies for the grafting of biomolecules on the gold are highly efficient and very promising for future use in biosensing.
