Special Issue Information

Dear Colleagues,

Recent advances in bioactive materials include the development of smart biomaterials that can respond to environmental stimuli, such as pH and temperature, allowing their properties to become accordingly adaptable. Bioactive materials are designed to mimic the natural extracellular matrix (ECM) found in tissues and organs, which can promote cell adhesion, proliferation, and differentiation. Biocompatible materials are placed into (endosseous) or onto (subperiosteal) the jawbone to support a crown, bridge, or artificial tooth, or to stabilize a diseased tooth. Materials are fabricated by BIOMIMETICS techniques, i.e., based on natural processes found in biological systems.

This Special Issue aims to provide a platform for researchers to share their latest findings and developments in the field of bioactive materials.  The Special Issue welcomes original research articles, reviews, and communications that cover a wide range of topics related to bioactive materials, including (but not limited to) the following:

Synthesis, preparation, and characterization techniques of bioactive materials;

Applications of bioactive materials in biomedical fields, such as drug delivery, tissue engineering, regenerative engineering for human and veterinary medicine, and materials related to dentistry.

The development of bioactive ceramics still poses challenges in finding a good compromise between bioactivity and mechanical robustness. Moreover, a facile, low-cost and energy-saving synthesis technique is still needed. This study concerns the synthesis of a bioactive material by growing a bioactive Na-Ca-Mg-Si-based ceramic matrix produced using the alkali-activation method on silicon nitride (Si3N4) particles. This technique simultaneously forms the matrix precursor and functionalizes the Si3N4 particles’ surface. The optimal strength–bioactivity compromise was found for the composition containing 60 wt.% Si3N4 and 40 wt.% of the matrix exhibiting good compressive strength of up to 110 MPa and extensive precipitation of hydroxyapatite on the sample surface after 7 days of soaking in simulated body fluid. This innovative approach merging strong non-oxide binary ceramics with the versatile and low-cost alkali-activation method holds great expectations for the future in biomaterials. Full article

The internal structure of the scaffolds is a key factor for bone regeneration. In this study, we focused on the space dimensionality within the scaffold that may control cell migration and evaluated the effects on the size and orientation of blood vessels and the amount of bone formation in the scaffold. The carbonate apatite scaffolds with intrascaffold space allowing one-dimensional (1D), two-dimensional (2D), or three-dimensional (3D) cell migration were fabricated by 3D printing. These scaffolds had the same space size, i.e., distances between the struts (~300 µm). The scaffolds were implanted into the medial condyle of rabbit femurs for four weeks. Both the size and orientation degree of the blood vessels formed in the scaffolds allowing 1D cell migration were 2.5- to 4.0-fold greater than those of the blood vessels formed in the scaffolds allowing 2D and 3D cell migration. Furthermore, the amount of bone formed in the scaffolds allowing 1D cell migration was 1.4-fold larger than that formed in the scaffolds allowing 2D and 3D cell migration. These are probably because the 1D space limited the direction of cell migration and prevented the branching of blood vessels, whereas 2D and 3D spaces provided the opportunity for random cell migration and blood vessel branching. Thus, scaffolds with 1D space are advantageous for inducing large and oriented blood vessels, resulting in a larger amount of bone formation. Full article
