“…In the case of 1000°C, the sample consists of two families of structures: particles with a size of few microns and acicular entities with a length up to 10 μm and nanometric thickness (Figure 4A). The emergence of the needles can be correlated with the deposition of a thin layer of CP phases on the surface of BC fibrils, which is fragmented as 1D structures when burning the polymeric core, as previously reported 13 . Increasing the temperature to 1200°C promotes the formation of a scaffold with improved mechanical strength due to the existence of a greater number of connections and more extensive interfaces.…”

Glass‐ceramic 3D porous structures were obtained by from a polymeric template, which was successively loaded with calcium phosphates, by chemical reaction and a dried gel based on barium and titanium by physical attachment. The resulting composite was subjected to a freeze‐drying procedure in order to maintain the spongy morphology. Under the effect of the subsequent thermal treatment at temperatures above 1000°C, the biocellulose membrane was completely removed, the mineral phases combined with each other through intense diffusion processes, and the mineral scaffolds acquired enough mechanical strength to become self‐sustained. The as‐prepared and thermally treated samples were characterized from physicochemical and biological point of view. The only crystalline phase emerged in the final masses was TiO2, while the microstructure was individualized as peculiar 3D architectures with porous and branched appearance. All prepared materials were proven to be biocompatible with the mesenchymal stem cells, showing no cytotoxic effect and suitability for the field of tissue engineering.

“…Biomedical sector -Further current developments in the BNC field mainly concern novel carrier materials for cell cultivation [122,137,138], encapsulation of cells/immobilization of enzymes [139], coating of medical devices [140], and the production of BNC materials using the well-known oxygen-transparent silicone supports [141,142]. In case of medical implants a lot of results is reported not only in the field of soft tissue implants (see Section In vivo scaffolds) but also regarding materials for bone regeneration [121,143,144].…”

Nanocelluloses are natural materials with at least one dimension in the nano-scale. They combine important cellulose properties with the features of nanomaterials and open new horizons for materials science and its applications. The field of nanocellulose materials is subdivided into three domains: biotechnologically produced bacterial nanocellulose hydrogels, mechanically delaminated cellulose nanofibers, and hydrolytically extracted cellulose nanocrystals. This review article describes today's state regarding the production, structural details, physicochemical properties, and innovative applications of these nanocelluloses. Promising technical applications including gels/foams, thickeners/stabilizers as well as reinforcing agents have been proposed and research from last five years indicates new potential for groundbreaking innovations in the areas of cosmetic products, wound dressings, drug carriers, medical implants, tissue engineering, food and composites. The current state of worldwide commercialization and the challenge of reducing nanocellulose production costs are also discussed.

“…CPs were non-toxic and suggested to be applied as cements/fillers. [18] Modification of BC culture media with hyaluronic acid 1% (w/w) and ex situ biomimetic precipitation of CPs BC fermentation medium was modified with hyaluronic acid 1% (w/w) and irradiated with gamma radiation in order to favor biomedical applications. After that, biomimetic precipitation of CP was performed from simulated body fluid (SBF), for perspectives in dental materials scaffolds applications.…”

Bacterial cellulose (BC) is a nanofibrous biomaterial biosynthetized by a series of acetic bacteria with unique properties with application in many tissue engineering purposes. Calcium phosphates (CPs), mainly hydroxyapatite, are bioceramics that possess similar composition of host bones and are able to stimulate osteoconduction and osteointegration to living tissues. Bacterial cellulose-calcium phosphates composites have caught the attention of researchers by their excellent mechanical properties and biocompatibility, being considered an excellent proposal to development of new synthetic grafts to bone tissue engineering. The minireview presented here focuses on various fabrication methods used to prepare and novel applications of BC-CPs composites and their applications in BTE.Keywords:
