Objectives: Calcium phosphate-based biomaterials (CaP) are the most widely used biomaterials to enhance bone regeneration in the treatment of alveolar bone deficiencies, cranio-maxillofacial and periodontal infrabony defects, with positive preclinical and clinical results reported. This systematic review aimed to assess the influence of the physicochemical properties of CaP biomaterials on the performance of bone regeneration in preclinical animal models.
Methods: The PubMed, EMBASE and Web of Science databases were searched to retrieve the preclinical studies investigating physicochemical characteristics of CaP biomaterials. The studies were screened for inclusion based on intervention (physicochemical characterization and evaluation) and reported measurable outcomes.
Results: A total of 1532 articles were retrieved and 58 studies were ultimately included in the systematic review. A wide range of physicochemical characteristics of CaP biomaterials was found to be assessed in the included studies. Despite a high degree of heterogeneity, the meta-analysis was performed on 39 studies and evidenced significant effects of biomaterial characteristics on their bone regeneration outcomes. The study specifically showed that macropore size, Ca/P ratio, and compressive strength exerted significant influence on the formation of newly regenerated bone. Moreover, factors such as particle size, Ca/P ratio, and surface area were found to impact bone-to-material contact during the regeneration process. In terms of biodegradability, the amount of residual graft was determined by macropore size, particle size, and compressive strength.
Conclusion: The systematic review showed that the physicochemical characteristics of CaP biomaterials are highly determining for scaffold's performance, emphasizing its usefulness in designing the next generation of bone scaffolds to target higher rates of regeneration.

The development of functional materials for osteoporosis is essential for effective bone remodeling. In this context, the extraction of biocompatible implantable biomaterials from bio-waste emerges as a valuable strategy, addressing both environmental challenges and promoting human health. The objective of this work was to evaluate the physicochemical properties of the added-value by-product biomaterial (SS-90), extracted from sardine scales (Sardina Pilchardus) and combined with chitosan (SS-90-CH).

Amino acid (AA)-based nanoparticles (NPs) hold promise in cancer therapy due to their excellent biocompatibility and the various therapeutic functions derived from AA monomers. Here, we developed a universal one-step method to synthesize AA-based NPs. We then constructed L-Arginine (L-Arg)/calcium phosphate (CaP) NPs to enhance cancer therapy through synergistic calcium overload to induce apoptosis and immunogenic cell death.

This study was aimed to analyze the structural and chemical properties of scaffolds prepared using the bovine rib bone. The bovine rib bone was extracted and processed by water jet washing, hydrogen peroxide treatment, and freeze drying to obtain porous scaffolds. Scanning electron microscopy analysis revealed that the scaffold was composed of interconnected trabeculae networks with an average pore diameter of 223 µm.

Titanium (Ti) and Ti alloy are the most widely used implant metals, but the limited bioactivity hinders the further clinical application. Aiming to enhance their osteogenesis, dual biomimetic strategies were utilized to decorate the surface of Ti by topological and biochemical cues. Firstly, a series of concentric circles with TiO nanotubes on Ti were fabricated by photolithography and anodic oxidation.
