“…An example application is given in Figure 7 whereby boron nitride nano-tubes (BNNT) were plasma surface treated to modify the BNNT wettability and adhesion characteristics. On account of its benefits, it has extensively been shown that plasma surface treatment can give rise to an enhanced biological cell response [130][131][132][133][134][135][136][137]. Having said this, Arefi-Khonsari et al [138] showed that certain polymers such as octadecyltrichlorosilane self-assembled monolayers (OTS-SAM) are much more resistant to this technique compared to polyethylene (PE), indicating that the successful implementation of this particular technique is material dependent.…”

On account of the recent increase in importance of biological and microbiological adhesion in industries such as healthcare and food manufacturing many researchers are now turning to the study of materials, wettability and adhesion to develop the technology within these industries further. This is highly significant as the stem cell industry alone, for example, is currently worth £3.5 million in the United Kingdom (UK) alone. This paper reviews the current state-of-the-art techniques used for surface treatment with regards to modulating biological adhesion including laser surface treatment, plasma treatment, micro/nano printing and lithography, specifically highlighting areas of interest for further consideration by the scientific community. What is more, this review discusses the advantages and disadvantages of the current techniques enabling the assessment of the most attractive means for modulating biological adhesion, taking in to account cost effectiveness, complexity of equipment and capabilities for processing and analysis.

“…4,5 However, one of the most widely used and simplest techniques is surface coating with extracellular matrix (ECM) components. 6 -9 Type VIII collagen is a short-chain, networkforming collagen originally identified as a product of ECs 10,11 and is thought to play a key structural role in the vasculature, where it is a major component of the subendothelial matrix and the tunica media.…”

Background-Essential to tissue-engineered vascular grafts is the formation of a functional endothelial monolayer capable of resisting the forces of blood flow. This study targeted ␣ 2 (VIII) collagen, a major component of the subendothelial matrix, and examined the ability of and mechanisms by which endothelial cells attach to this collagen under static and dynamic conditions both in vitro and in vivo. Methods and Results-Attachment of human endothelial cells to recombinant ␣ 2 (VIII) collagen was assessed in vitro under static and shear conditions of up to 100 dyne/cm 2 . ␣ 2 (VIII) collagen supported endothelial cell attachment in a dose-dependent manner, with an 18-fold higher affinity for endothelial cells compared with fibronectin. Cell attachment was significantly inhibited by function-blocking anti-␣ 2 (56%) and -␤ 1 (98%) integrin antibodies but was not RGD dependent. Under flow, endothelial cells were retained at significantly higher levels on ␣ 2 (VIII) collagen (53% and 51%) than either fibronectin (23% and 16%) or glass substrata (7% and 1%) at shear rates of 30 and 60 dyne/cm 2 , respectively. In vivo studies, using endothelialized polyurethane grafts, demonstrated significantly higher cell retention rates to ␣ 2 (VIII) collagen-coated than to fibronectin-coated prostheses in the midgraft area (PϽ0.05) after 24 hours' implantation in the caprine carotid artery. Conclusions-These

“…Consequently, fluoropolymers have wide applications in modern technologies ranging from building, automotive and aerospace industries to optics and microelectronics [4][5][6]. In several areas of surface coatings technology, such as antifouling and easily cleaned coatings addition, fluoropolymers have attracted a great deal of attention of researchers [7][8][9][10].…”

Semi-interpenetrating polymer networks (SemiIPNs) based on fluorine-containing polyacrylate and epoxy resin were synthesized by the simultaneous polymerization of fluorine-containing acrylate and epoxy resin. Fourier transform infrared (FTIR) spectrometry and X-ray photoelectron spectroscopy (XPS) analyses proved that the fluorine-containing groups have been introduced into Semi-IPNs successfully. In addition, XPS analysis intuitively showed that the fluorine content of the film-air interface of the interpenetrating fluorine-containing polyacrylate and epoxy resin networks (FPAER-SIPNs) film was much higher than that of the film-glass interface. It is noted that the introduction of fluorine-containing groups significantly improved the hydrophobic property of polymer networks. Moreover, when the fluorine content increased, the contact angle of water on FPAER-SIPNs film was increased obviously and the water uptake was decreased gradually. These results indicated that introducing fluorine-containing groups to SIPNs has potential advantage for improving the surface properties of epoxy resin.
