“…On the basis of the hydration surface and biomimetic, hydrogel grafted with zwitterionic could minimize the interactions between the protein and the surface of the bulk materials, maintain the normal conformation of proteins . Liu et al . improved the protein adsorption on the surface from 4.25 μg cm −2 to 1.67–1.69 μg cm −2 ).…”

“…Zwitterionic containing both positively and negatively charged groups can bind to water molecules more strongly and stably than the other materials via electrostatically induced hydration and effectively prevent the adhesion of proteins and cells . Liu et al . fabricated the zwitterionic brushes on the PU surface, and the protein adsorption decreased significantly from 4.25 μg cm −2 to 1.67–1.69 μg cm −2 .…”

To improve the antifouling property, polyvinyl alcohol hydrogel was successfully grafted with [2-(methacryloyloxy) ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide (MEDSAH) via photoinduced electron transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization under a 10 W blue (450-460 nm) light-emitting diodes. It is surprising that the reaction could be performed in the presence of oxygen, which meant that the reaction has a great prospect of industrialization. The highest grafting percentage (GP) was 55.77% by adding triethylamine and changed the MEDSAH usage in the absence of oxygen. Thermal gravimetric analysis exhibited that grafted MEDSAH affects the thermal property of PVA hydrogel. Also, there was no influence on the ultraviolet-visible transmittance, and the PVA-g-pMEDSAH hydrogel became hydrophilicity after grafting. Moreover, in vitro cytotoxicity of both PVA and PVA-g-pMEDSAH hydrogel was noncytotoxic according to ISO 10993-2009. The antifouling property of PVA-g-pMEDSAH hydrogel was increased about 53.05%. Thus, the PVA-g-pMEDSAH hydrogel can be an ideal optical biomaterial candidate.

“…The functionalization of PU films was performed by SI-ATRP based on the procedure described in our previous work [ 38 ]. For this purpose, 1.0 mmol of BPY and several pieces of PU-Br were added to a Schlenk flask, which was then evacuated using liquid nitrogen cryotherapy and back-filled with nitrogen.…”

Diseases and complications related to catheter materials are severe problems in biomedical material applications, increasing the infection risk and medical expenses. Therefore, there is an enormous demand for catheter materials with antibacterial and antifouling properties. Considering this, in this work, we developed an approach of constructing antibacterial surfaces on polyurethane (PU) via surface-initiated atom transfer radical polymerization (SI-ATRP). A variety of cationic polymers were grafted on PU. The biocompatibility and antifouling properties of all resulting materials were evaluated and compared. We also used a theoretical algorithm to investigate the anticoagulant mechanism of our PU-based grafts. The hemocompatibility and anti-biofouling performance improved at a 86–112 μg/cm2 grafting density. The theoretical simulation demonstrated that the in vivo anti-fouling performance and optimal biocompatibility of our PU-based materials could be achieved at a 20% grafting degree. We also discuss the mechanism responsible for the hemocompatibility of the cationic brushes fabricated in this work. The results reported in this paper provide insights and novel ideas on material design for applications related to medical catheters.

“…[28][29][30][31][32] They constitute a strong reinforcement of the metal surface in aggressive environments. [33][34][35][36][37] To confer to the surface additional properties for applications, e.g., antifouling, 38,39 lubrication, 40,41 cell culture 42,43 or even cell differentiation, 44 appropriate polymer coatings are also used. One way to generate theses polymers is the surface-initiated controlled radical polymerization (SI-ATRP) which leads to the growth of polymer brushes with a good level of control over chain length, grafting density, and molecular architecture.…”

Electrografting of mixed organophosphonic monolayers for SI-ATRP of 2-methacryloyloxyethyl phosphorylcholine

et al. 2019

Nitinol (NiTi), one of the most important alloys for biomedical applications, is still hampered by its surface nickel inclusions, making it sensitive to pitting corrosion and leading therefore to the release of potentially carcinogenic Ni 2+ ions. In this work, we assess the impact of the combination of electrografted mixed self-assembled monolayers (SAMs) on NiTi followed by a polymer coating formed by surfaceinitiated atom transfer radical polymerization (SI-ATRP). The molecular ratio of 11-(2-bromoisobutyrate)-undecyl-1-phosphonic acid (BUPA) to 11-decylphosphonic acid (C 10 P) on the electroassisted elaboration of the (BUPA/C 10 P)-NiTi-SAMs has been optimized. A small amount of BUPA (20%) appears to be the most promising condition, as it provides an efficient corrosion resistance and promotes the SI-ATRP of 2-methacryloyloxyethyl methacrylate (MPC). This confers to the surface hydrophilic properties and corrosion resistance close to those NiTi-SAMs when long polymerization times are used (‡ 6 h).
