“…The final concentration of Ch solution was 0.1 mg mL -1 and the measured pH 3.1. It was the same as that used in our previous studies [2,28] as well as in the measurements conducted by the other authors [29,30]. Such concentration was found to be sufficiently high to provoke a possible expansion of the CsA monolayers and to inspect the temperature effects.…”

“…Synthetic and biological covering materials have been investigated to reduce the thrombosis and restenosis during the implant placement. Chitosan (Ch) has been proposed as a suitable material for implant surface coating for enhancement of biocompatibility to the surrounding tissues [1,2]. Since chitosan is obtained by N-deacetylation of chitin, the natural polymer present in arthropod and insect exoskeletons, crustacean shells and some fungi cell walls, its biocompatibility is strictly dependent on origin, extraction method and purity [3].…”

Chitosan (Ch) is a polysaccharide mainly used in cosmetics, biotechnology and medicine owing to its biocompatibility, biodegradability and low cytotoxicity. One of the challenges is the development of mechanisms responsible for its action in biomedical applications. In this aspect, it is important to get more profound insight into the chitosan interactions with peptide drugs at the molecular level. The drug of interests was a cyclosporine A (CsA) known for its effective immunosuppressive action against transplant rejection. In this study, the Langmuir technique was used to determine the interactions between Ch (dissolved in the subphase) and the monomolecular films of CsA spread at the air-chitosan solution interface. The surface pressure versus the area per molecule (p-A) measurements of the CsA monolayers on the subphase with or without Ch was conducted at 20°C and 37°C. The Ch insertion into the CsA monolayers was monitored by relative changes in the DA A area and the compression modulus. The findings demonstrate that the presence of Ch in the subphase provides the CsA monolayer expansion and affects the molecular packing and ordering in the temperaturedependent way. The temperature increase induces conformational changes in the peptide monolayers being a decisive factor which influences the kind and strength of interactions between Ch and CsA.

“…To further characterize the surface polarity quantitatively, the surface free energy and its components were determined from the theoretical model developed by van Oss et al [ 55,56 ] As displayed in Figure 7B, the polar component and dispersive component of surface energy exhibits similar trend with contact angles of diiodomethane and water, respectively. Furthermore, when the CCh/PEI ratio was 1:1, the maximum value of total surface energy and its polar component was 54.9 and 19.7 mJ m −2 , respectively.…”

Substantial amount of polyethylene terephthalate/cotton (PET/cotton) blend fabrics have been handled as waste especially in recent decades on account of the technological barrier and/or low economic benefit of recycling PET from PET/cotton fabrics. Herein, a facile and effective approach was utilized to modify PET/cotton fabrics with co‐deposition of polyethyleneimine (PEI) and catechol (CCh) to improve the interfacial bonding of fiber‐matrix. The surface morphology and composition of fabrics were investigated by FESEM, ATR/FTIR, and XPS. Meanwhile, the surface properties were analyzed via dynamic contact angle. The results indicated that the PEI‐CCh co‐deposition aggregates were modified onto fabric surface through the synergy of intermolecular hydrogen bonding and π‐π stacking. Interlaminar shear strength (ILSS) and interfacial shear strength (IFSS) of modified PET/cotton reinforced composites were 39.71% and 50.25% higher than that of untreated PET/cotton reinforced composites, respectively. Furthermore, the enhancement mechanisms of composites are systematically discussed.

“…Santos and co-workers constructed plasmaactivated coatings with the high mechanical properties using plasma deposition technique [33]. Recently, Jurak et al reported mixed chitosan/phospholipid coatings on the air plasma-activated PET surface [35]. However, this method is hard to tailor the coated polymer material due to the wasted material during the process of transportation.…”

“…Plasma deposition strategy has been widely employed to prepare the bioactivation of materials by utilizing carbon precursor gases [33,34]. Clearly, incorporating natural compounds of native tissues is a more profitable host tissue response [35,36]. Moreover, the method exhibits the potential to tailor polymer coating to meet specific needs [33].…”

Implanting a metal stent plays a key role in treating cardiovascular diseases. However, the high corrosion rate of metal-based devices severely limits their practical applications. Therefore, how to control the corrosion rate is vital to take full advantages of metal-based materials in the treatment of cardiovascular diseases. This review details various methods to design and construct polymer-coated stents. The techniques are described and discussed including plasma deposition, electrospinning, dip coating, layer-by-layer self-assembly, and direct-write inkjet. Key point is provided to highlight current methods and recent advances in hindering corrosion rate and improving biocompatibility of stents, which greatly drives the rising of some promising techniques involved in the ongoing challenges and potential new trends of polymer-coated stents.
