Natural endothelium provides multifaceted antithrombotic functions through nitric oxide/ prostacyclin secretion to inhibit platelet activation, glycosaminoglycan mediated anticoagulation, and tissue-type plasminogen activator driven fibrinolysis. Therefore, surfaces mimicking these multiple endothelial functions are expected to have enhanced antithrombotic properties. In this study, polyvinyl chloride surface was rendered porous through solvent/nonsolvent-induced phase separation and loaded with a metal-organic framework, CuBTTri to catalyze nitric oxide release from a precursor. Furthermore, using layer-by-layer self-assembly, multiple bilayers of a poly(lysine-<em>co</em>-oligo(ethylene glycol) methyl ether methacrylate) copolymer (fibrinolysis-promoting), and sodium heparin (endothelial cell growth-promoting), were deposited on the un-etched side of the polyvinyl chloride.

Films containing poly(acrylic acid) (PAA) chains and polystyrene (PS) colloidal nanoparticles were analyzed using microbeam small-angle X-ray scattering (SAXS) and atomic force microscopy (AFM) to probe the impact of evaporation rates and colloid sizes on stratification behavior. Under slow drying conditions, particle-on-top stratification was observed, consistent with a diffusive model of stratification behavior. Conversely, moderate evaporation rates resulted in non-stratified configurations for certain mixtures. Fast evaporation, achieved by drying at elevated temperatures, induced polymer-on-top stratification, which aligns with predictions from simulations.

Although bone tissue has a certain capacity for self-repair, artificial substitute materials of bone are still required to facilitate the repair, especially for large-scale bone defects. At present, tissue engineering-related materials that mimic the structure, mechanical properties, and biological characteristics of natural bone have been widely used for addressing bone defects and promoting in situ bone regeneration. Hydrogels that emulate the properties of the extracellular matrix are prevalent materials in bone tissue engineering, with a particular emphasis on those crosslinked through HRP-mediated, which have garnered considerable interest due to their high efficiency of preparation, mild reaction conditions, controllable properties, and excellent biocompatibility. However, the suboptimal osteogenic capability inherent in HRP-mediated crosslinked hydrogels necessitates the integration of additional osteogenic activity materials, such as biological calcium phosphates, biomimetic scaffolds, growth factors, synthetic peptides, and nanomaterials, to bolster the hydrogel scaffolds' osteogenic potential. This manuscript provides a concise overview of the standard methodologies for crafting injectable hydrogels, highlighting the HRP catalytic reaction mechanism, and strategies for modulating hydrogel attributes. Furthermore, this paper delves into the recent advancements in HRP-mediated crosslinked hydrogel scaffolds, highlighting their role in bone defect repair within the realm of bone tissue engineering.
