“…PU's cytotoxicity has been extensively investigated, including in vivo and in vivo studies. For example, PU elastomer was previously evaluated for its blood biocompatibility [61,62]. In another case study, mouse fibroblast cell lines and human saphenous-vein endothelial cells (HSVECs) were used for culture with various commercial PUs.…”

Polyurethanes (PU) have properties that make them promising in biomedical applications. PU is recognized as one of the main families of blood and biocompatible materials. PU plays a vital role in the design of medical devices in various medical fields. The structure of PU contains two segments: soft and hard. Its elastomeric feature is due to its soft segment, and its excellent and high mechanical property is because of its hard segment. It is possible to achieve specific desirable and targeted properties by changing the soft and hard chemical structures and the ratio between them. The many properties of PU each draw the attention of different medical fields. This work reviews PU highlighted properties, such as biodegradability, biostability, shape memory, and improved antibacterial activity. Also, because PU has a variety of applications, this review restricts its focus to PU’s prominent applications in tissue engineering (TE), cardiovascular medicine, drug delivery, and wound healing. In addition, it contains a brief review of PU’s applications in biosensors and oral administration.

“…Ji [6] has previously studied Graphene Oxide/Hydroxyapatite-AZ91D Magnesium alloy (GO/HA-AZ91D), and the corrosion resistance of the composite coating is significantly improved. According to the definition of International Standards Organization (ISO), blood compatibility [7] refers to the required reaction of blood to exogenous substances or materials, and generally refers to the compatibility between materials and components in blood. The main visible components of blood are blood cells, including red, white and platelets, which play an important role in maintaining nutrient and oxygen supply, inflammation and clotting, respectively.…”

Magnesium alloy has excellent physical and mechanical properties and is expected to become a new generation of medical degradable materials. In this paper, the blood compatibility analysis of Graphene Oxide(GO)/Hydroxyapatite(HA)-AZ91D was carried out to improve the blood compatibility of magnesium alloy materials. AZ91D was used as the control group and GO/HA-AZ91D was used as the experimental group. The two samples were studied in vitro by hemolysis rate test, cell proliferation test, NO release and T-AOC test. The results combined with the work of the research group showed that the blood compatibility and cell compatibility of the GO/HA-AZ91D group were significantly improved, providing an effective idea for future corrosion resistant coatings on magnesium alloys.

Molecular brushes (MBs) are a unique type of branched macromolecules which graft polymeric chains onto a linear polymeric backbone densely. Crowded tethered side chains generate strong steric repulsion and force the backbone to stretch out, resulting in a persistent cylindrical shape and low density of entanglements of brushes. Owing to the unique rheological and mechanical properties and self-assembly behaviors, MBs show a great potential in nanotechnology and surface science. Herein, the synthesis of novel MBs of polyacrylate-g-poly(6-(4-butyl-4'-oxyazobenzene)hexylacrylate)/barbituric acid (PA-g-PAzo/Bar) was reported, in which PAzo brushes and hydrogen-bonding barbituric acid were grafted using the combination of concurrent atom transfer radical polymerization (ATRP) and click reaction. MBs-based aggregates change from cylinder to compound micelle by increasing the concentration. It is interesting that morphology transitions of cylinder-to-porous nanosheet and compound micelle-to-pearl-necklace were observed upon UV irradiation, that was ascribed to the trans-to-cis isomerization of PAzo brushes.
