Cellulose/chitosan composite, as a mature commercial antibacterial dressing, is an important type of wound repair material. However, how to achieve the perfect compound two components and improve activity major, lingering issue. In this study, bifunctional group modified bacterial cellulose (DCBC) was prepared by carboxymethylation selective oxidation. Further, chitosan (CS) compounded in network DCBC self-crosslinking form dialdehyde carboxymethyl cellulose/chitosan composites (S-DCBC/CS)....
Abstract Bacterial infection and inferior osseointegration are major complications associated with titanium (Ti) based implants. Although surface‐engineered zinc oxide (ZnO) nanorods exhibit remarkable antibacterial ability, their potential biomedical applications hampered by pronounced cytotoxicity. Herein, inspired the in vivo degradation process of znic, ZnO converted into thermodynamically more stable phosphate (Zn 3 (PO 4 ) 2 ）through a simple hydrothermal treatment hydrogen solution....
Uncontrollable hemorrhage leads to high mortality and thus effective bleeding control becomes increasingly important in the military field civilian trauma arena. However, current hemostats not only present limitation when treating major bleeding, but also have various side effects. Here we report a self-expanding porous composites (CMCP) based on novel carboxymethyl cellulose (CMC) fibers acetalized polyvinyl alcohol (PVA) for lethal control. The CMC with uniform fibrous structure, liquid...
Effective strategy of hemostasis and promoting angiogenesis are becoming increasingly urgent in modern medicine due to millions deaths caused by tissue damage inflammation. The adhesive has been favored as an optimistic efficient path stop bleeding, while, current presents limitations on wound care or potential degradation safety clinical practice. Therefore, it is great significance construct multifunctional address the issues. Based pro-angiogenic property l-Arginine (L-Arg), this study,...
The in vitro degradation and cytotoxicity of bacterial cellulose (BC) its products were studied for potential applications bone tissue engineering. Emission scanning electron microscope was used to observe the morphology original materials their products. evaluated by measuring concentration reducing sugar using ultraviolet spectrophotometer. Bone forming osteoblast (OB) cells infinite culture cell line L929 fibroblasts measure MTT assay. Both types proliferated normally with BC a graded...
The main objective of this study is investigate the behavior Zeta Potential MWCNT modified with SDS(Sodium Dodecyl Sulfate) and CTAB(Cetyl Tetraethyl Ammonium Bromide) in presence PVA. Full hydrolyzed PVA was used. As a result, adding CNT solution led to decrease Potential. suspended colloid varied from 42.00mV 6.48mV -45.00mV -6.4mV at 1.5% concentration PVA; according changing pH, dropped near zero pH 3 11. has strong influence reduction ZP solution. MWCNT-PVA 33.30mV, -35.69mV 0.01%...
Cell transplantation is an effective strategy to improve the repair effect of nerve guide conduits (NGCs). However, problems such as low loading efficiency and cell anoikis undermine outcomes. Microcarriers are efficient 3D culture scaffolds, which can also prevent by providing substrate for adhesion during transplantation. Here, we demonstrate first time microcarrier-based in peripheral repair. We prepared macroporous chitosan microcarriers (CSMCs) emulsion-phase separation method, then...
Titanium (Ti) with nanoscale structure on the surface exhibits excellent biocompatibility and bone integration. Once implanted, surgical implantation may lead to bacterial infection inflammatory reaction, which cause implant failure. In this work, irregular nanorod-shaped ZnO nanoparticles were doped into TiO2 nanotubes (TNTs) inner diameter of about 50 nm by electro-deposition. The antibacterial properties incorporated (TNTs/ZnO) evaluated using Staphylococcus aureus (S. aureus). Zn ions...
Three-dimensional (3D) printing provides a new approach of fabricating implantable products because it permits flexible manner to extrude complex and customized shapes the tissue scaffolds. Compared with other printable biomaterials, polyurethane elastomer has several merits, including excellent mechanical properties good biocompatibility. However, some intrinsic behavior, especially its high melting point slow rate degradation, hampered application in 3D printed engineering. Herein, we...
Irregular articular cartilage injury is a common type of joint trauma, often resulting from intense impacts and other factors that lead to irregularly shaped wounds, the limited regenerative capacity mismatched shape scaffods have contributed unsatisfactory therapeutic outcomes. While injectable materials are traditional solution adapt irregular defects, they limitations, lack porous microstructures favorable for rapid proliferation cells. In this study, an polyurethane scaffold named...
Demineralized bone matrix (DBM) is a decalcified allo/xenograft retaining collagen and noncollagenous proteins, which has been extensively used because of its osteoconductive osteoinductive properties. Calcium sulfate (CaSO4, CS) synthetic substitute in healing with biocompatible, nontoxic, bioabsorbable, osteoconductive, good mechanical characteristics. This study aims to prepare DBM/CS composite graft material moldable putty form without compromising the peculiar properties DBM CS. For...
Extracellular matrix (ECM) components have become important candidate materials for use as neural scaffolds tissue engineering. In the current study, we prepared cauda equina-derived ECM production of scaffolds. Natural porcine equina was decellularized using Triton X-100 and sodium deoxycholate, shattered physically, made into a suspension by differential centrifugation. The decellularization procedure resulted in removal >94% nuclear material preserved extracellular collagen sulfated...
