“…The single sample (2), almost without growth is cross-linked with 4 wt % ES40 and 2 wt % PEG-silane, whereas the two others (1 and 1') are almost totally covered by algae. It is well known that PEG-chains in water media are strongly solvated, which makes non-specific protein adsorption difficult [5]. Probably for this reason, the presence of PEG-chains covalently bonded to the poly(siloxane) matrix creates the strong antigrowth effect of coating 2.…”

“…Variety approaches to the reduction of marine biofilm formation are currently known, including physical, physical-chemical, and enzymatic ones, mostly biomimetic and/or based on use of natural derivatives, such as natural biocides, surfactants, and quorum sensing inhibitors [4,5]. Unfortunately, no report could be found in the special literature about a surface that is able to completely stop the development of marine biofilms, even if it contains biocide.…”

Siloxane fouling release coatings are currently the only viable non-toxic commercial alternative to toxic biocide antifouling paints. However, they only partially inhibit biofouling since biofilms remain a major issue. With the aim to improve the bacterial resistance of siloxane coatings modified with non-ionic surfactant (NIS), antioxidant (AO) or both NIS/AO, the ability of PEG-silane co-cross-linker was investigated to reduce Cobetia marina adhesion and multispecies biofilm formation from natural seawater. Surface physical-chemical and physical-mechanical parameters relevant to bio-adhesion were estimated before the testing of the biofilm formation. Slightly reduced biofilm from C. marina and sharply reduced multispecies biofilm, formed in natural sea water, were found on the PEG-silane co-cross-linked coatings without modifying additives. However, both C. marina growth and biofilm formation from natural sea water were sharply reduced on the PEG-silane co-cross-linked coatings containing NIS or AO, even more, no C. marina adhesion was seen on the coating containing NIS and AO simultaneously. Possible explanations of the observed effects are presented in this article. It was concluded that the PEG-silane co-cross-linker, toghether with NIS and AO, can be used as an efficient tool to additionally reduce the bioadhesion of Gram-negative marine bacteria and multispecies biofilm formation on siloxane antifouling coatings.

“…The contact area of adhesion was displaced by the water; this led to decreasing adhesion strength. In addition, Ditsche and Summers summarized the adhesion mechanism involved in the electrostatic forces, chemical bonding, van der Waals forces, and so on in the adhesion system, but the majority of these interactions were confounded by the infiltration of water into the joint, and this results in adhesive failure in most synthetic adhesives …”

Polyurethane (PU) has been widely used as a glue in various areas. However, adhesion in the presence of water is greatly impeded and results in most synthetic adhesive failure. In this study, we designed and synthesized a novel PU construction; underwater PU adhesives were created by the incorporation of synthetic glycerol monomethacrylate (GMA). Furthermore, the urethane structure helped the adhesive eliminate the interfacial water barrier through interactions that were stronger than hydrogen bonding, and GMA as a crosslinking agent was used to generate post-covalent-crosslinking networks through radical polymerization. This enhanced the cohesion so the diffusion of water molecules could be overcome. Fourier transform infrared spectroscopy, thermogravimetric analysis, underwater adhesion measurements, and tensile tests were used to characterize the chemical and mechanical properties of the as-obtained adhesive. This led to an adhesive with a better mechanical strength and interfacial adhesion in water, and the results show that the mechanical properties (tensile strength, Young's modulus, and tensile elongation) of the GMA-PU adhesive were higher than those of the pure PU. As for the 4% GMA, the tensile strength was enhanced by 24.3% and the elongation was enhanced by 125.23% over those of the pure PU. This confirmed that the incorporation of GMA into the PU matrix indeed induced increasing cohesion, and the sample's adhesive strength was 21.19 6 3.9 MPa; this indicated a superior adhesive strength over that of the pure PU. In addition, we can foresee that underwater adhesion will play an important role in prospective surgery and engineering areas. V C 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46579.

“…It is nontoxic and approved by the Food and Drug Administration (FDA) [151,165]. Due to its biocompatibility and its versatility, PEG is typically combined or copolymerized with other polymer systems to achieve desired properties such as solubility [166], tunable drug release rate [167], and resistance to bioadhesion [168]. PEG is used in wound dressings since it can retain water and keep the wound environment moist [169].…”

Antibiotic Delivery Strategies to Treat Skin Infections When Innate Antimicrobial Defense Fails

et al. 2020

The epidermal skin barrier protects the body from a host of daily challenges, providing protection against mechanical insults and the absorption of chemicals and xenobiotics. In addition to the physical barrier, the epidermis also presents an innate defense against microbial overgrowth. This is achieved through the presence of a diverse collection of microorganisms on the skin (the “microbiota”) that maintain a delicate balance with the host and play a significant role in overall human health. When the skin is wounded, the local tissue with a compromised barrier can become colonized and ultimately infected if bacterial growth overcomes the host response. Wound infections present an immense burden in healthcare costs and decreased quality of life for patients, and treatment becomes increasingly important because of the negative impact that infection has on slowing the rate of wound healing. In this review, we discuss specific challenges of treating wound infections and the advances in drug delivery platforms and formulations that are under development to improve topical delivery of antimicrobial treatments.
