“…The discharge power used for each discharge gas was determined through voltage-charge plots (Lissajous figures) and are summarized in table 6 [47][48][49] . As can be seen, the applied discharge power is not the same for each discharge gas due to differences in electrical breakdown voltages.…”

The surface properties of electrospun scaffolds can greatly influence protein adsorption and thus strongly dictate cell-material interactions. In this study, we aim to investigate possible correlations between the surface properties of argon, nitrogen and ammonia/helium plasma-functionalized polycaprolactone (PCL) nanofibers (NFs) and their cellular interactions by examining the protein corona patterns of the plasma-treated NFs as well as the cell membrane proteins involved in cell proliferation. As a result of the performed plasma treatments, PCL NFs morphology was preserved while wettability was improved profoundly after all treatments because of the incorporation of polar surface groups. Depending on the discharge gas, different types of groups are incorporated which influenced the resultant cell-material interactions. Argon plasma-functionalized PCL NFs, only enriched by oxygen-containing functional groups, were found to show the best cell-material interactions, followed by N2 and He/NH3 plasma-treated samples. SDS-PAGE and LC-MS clearly indicated an increased protein retention compared to non-treated PCL NFs. The nine proteins best retained on plasma-treated NF are important mediators of extracellular matrix interaction, illustrating the importance thereof for cell proliferation and viability of cells. Finally, 92 proteins that can be used to differentiate the different plasma treatments are clustered and subjected to a gene ontology study, illustrating the importance of keratinization and extracellular matrix organization.

The current generation of tissue engineered additive manufactured scaffolds for cartilage repair shows high potential for growing adult cartilage tissue. This study proposes two surface modification strategies based on non-thermal plasma technology for the modification of poly(ethylene oxide terephthalate/poly(butylene terephthalate) additive manufactured scaffolds to enhance their cell-material interactions. The first, plasma activation in a helium discharge, introduced non-specific polar functionalities. In the second approach, a carboxylic acid plasma polymer coating, using acrylic acid as precursor, was deposited throughout the scaffolds. Both surface modifications were characterized by significant changes in wettability, linked to the incorporation of new oxygen-containing functional groups. Their capacity for chondrogenesis was studied using ATDC5 chondroblasts as a model cell-line. The results demonstrate that the carboxylic acid-rich plasma coating had a positive effect on the generation of the glucoaminoglycans (GAG) matrix and stimulated the migration of cells throughout the scaffold. He plasma activation stimulated the formation of GAGs but did not stimulate the migration of chondroblasts throughout the scaffolds. Both plasma treatments spurred chondrogenesis by favoring GAG deposition. This leads to the overall conclusion that acrylic acid based plasma coatings exhibit potential as a surface modification technique for cartilage tissue engineering applications.

“…It is an environmentally friendly method due to the solvents-free requirement and the low temperature of process. This method diminishes the number of processes because it integrates cleaning, the etching of the substrate, and the deposition of the coating, in one process [4,18,19,21,22]. Plasma polymerization is achieved by introducing organic monomer precursors (vapor) into a plasma reactor leading to the uniform deposition of so-called plasma polymers on the surface of WO3 powder substrates.…”

This study reports on the preparation of hybrids of tungsten trioxide/polythiophene (WO3/PTh) and tungsten trioxide/polyfuran (WO3/PFu) using a rotating capacitively-coupled radio frequency (rf) plasma process. The prepared hybrid characteristics were measured using scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS) and Xray diffraction analysis (XRD). WO3, WO3/PTh, and WO3/PFu thin films were deposited onto flexible substrates using an electron beam evaporation technique for high electrochromic performance purposes. The effect of thiophene and furan moieties on the optical and electrochromic properties of flexible hybrid-based ECDs was investigated using optical and electrochemical measurements. The WO3/PTh-based ECD, in particular, showed marked improvements in cathodic electrochromism over WO3-based ECD: an optical contrast of 33% at 750 nm, faster switching times (bleaching time: 1.63 s, coloration time: 0.41 s), and a coloration efficiency of 502 cm 2 /C.
