• as potential candidates for bone TE due to osteoblast attachment and corrosion resistance [141]. Wan et al. used bacterial cellulose as a template to synthesize calcined mesoporous TiO2 nanotubes and constructed a nanotube-based scaffold using a template-assisted sol–gel method [142]. In addition to

• ]. As a result, the surface area of this hybrid structure is expected to increase and expand its wavelength response up to the visible range. Bacterial cellulose shows the ability to act as a metal oxide nanoparticle support due to its high surface-area-to-volume ratio with a fibre diameter in the range

• of 40–70 nm, high mechanical strength and super-hydrophilicity properties [123]. Its ultrafine three-dimensional network provides bacterial cellulose with a high specific surface area, owing to the well-separated nano- and microfibrils. Besides, the presence of –OH binding sites and a fibrous network

• can facilitate the adsorption of metal oxide to its surface. Thus, Li et al. [123] proposed the immobilization of TiO2 nanoparticles on a fine fibrous network of bacterial cellulose via hydrogen bonds and electrostatic adsorption effect for the photocatalytic degradation of reactive X-3B. TiO2

• bacterial cellulose. The smallest particle size was obtained with a 71% RDX/gelatine mixture. However, increasing the content of RDX leads to an increase in the particle size and the maximum RDX loading tested was 91% resulting in a mean particle diameter of 50 nm. The sensitivity of this composite towards

• impact and friction was reduced by two times, therefore questioning the reactivity. Nevertheless, further efforts were made to replace the bacterial cellulose with an energetic matrix. Crystallization in solution allows the formation of large crystals by growth, thus allowing more parametric studies
