- Abstract:
- ... The ability of mimicking the extracellular matrix architecture has gained electrospun scaffolds a prominent space into the tissue engineering field. The high surface-to-volume aspect ratio of nanofibers increases their bioactivity while enhancing the bonding strength with the host tissue. Over the years, numerous polyesters, such as poly(lactic acid) (PLA), have been consolidated as excellent matr ...

- Abstract:
- ... Soft tissue integration is critical for the long-term retention of dental implants. The surface properties including topography and wettability can impact soft tissue sealing. In our work, a thermal hydrogenation technique was applied to modify anodized titanium dioxide nanotubes (TNTs). However, the effects of the hydrogenated surface on soft-tissue cells remain unclear. The aim of the present st ...

- Abstract:
- ... Polyetheretherketone (PEEK) has the potential to replace traditional metallic materials as an orthopedic and dental implant because its elastic modulus is similar to natural bone, although its intrinsic bioinertness hampers its clinical application. In this study, sulfonate groups were introduced onto the PEEK surface through a single-step ultraviolet-initiated graft polymerization of vinylsulfoni ...

- Abstract:
- ... Polyetheretherketone (PEEK) is considered to be a prime candidate with the potential to replace biomedical metallic materials as an orthopedic and dental implant on account of its elastic modulus similar to that of human cortical bone. Unfortunately, its biomedical application is impeded by the bioinert surface property and inferior osteogenic activity. In this work, phosphate groups were incorpor ...

- Abstract:
- ... Nature derived biopolymers such as polysaccharides and collagen have attracted considerable attention in biomedical applications. Despite excellent biocompatibility and bioactivity, their poor mechanical properties could not meet the requirement for skin regeneration. In this study, cellulose nanocrystal (CNC) was incorporated into the calcium cross-linked sodium alginate/gelatin (SA/Ge) scaffold ...

- Abstract:
- ... Micro/nanotopographical modification of biomaterials plays an essential role in the improvement of implants’ cytocompatibility. In this paper, hierarchical micro/nanostructured surface was constructed to improve the titanium alloy cytocompatibility, which combined sandblasting, acid etching, and alkali heat treatment. The surface features were characterized using scanning electron microscope (SEM) ...

- Abstract:
- ... Interaction between the surface of implants and biological tissues is a key aspect of biomaterials research. Apart from fulfilling the non-toxicity and structural requirements, synthetic materials are asked to direct cell response, offering engineered cues that provide specific instructions to cells. This work explores the functionalization of titanium with integrin-binding peptidomimetics as a no ...

- Abstract:
- ... For skin tissue engineering, an ideal scaffold should mimic the natural extracellular matrix of the native skin. In this study, we reported a novel elastic sub-micron fiber scaffold blending poly (ε-caprolactone-co-lactide) (PLCL) and Pluronic at different ratios by electrospinning. PLCL and Pluronic were co-electrospun with the ratio of 100/0, 99/1, 95/5, 90/10, 85/15, and 75/25. These scaffolds ...

- Abstract:

However, introduction of a specific surface topography may disturb the correlation between ECM proteins adsorption and cells adhesion on a given surface. In present study, lotus-leaf-like topography was introduced on the surface of a biodegradable material, poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PH ...

- Abstract:

A thin film of polystyrene (PS) prepared on a solid substrate was exposed to UFB water for 2 days at room temperature. The PS surface was characterized by X-ray photoelectron spectroscopy (XPS), static contact ang ...

- Abstract:
- ... Decorin is a structural and functional proteoglycan (PG) residing in the complex network of extracellular matrix (ECM) proteins in many connective tissues. Depending on the protein core and the glycosaminoglycan chain, PGs support cell adhesion, migration, proliferation, differentiation, ECM assembly and growth factor binding. For applications in tissue engineering, it is crucial to develop reliab ...
