• ]. Review Bone structure Bone is a hard tissue that contains different kinds of cells including osteoblasts, osteocytes, and osteoclasts (Figure 1) [26]. The inorganic hydroxyapatite and organic type I collagen components are vital to bone tissue. The bone biomineralisation activities are formed by

• mechanical strength and cell adhesion. Importantly, the developed biocomposites have excellent antimicrobial activity [111]. AgNP-loaded fibrillar collagen–chitosan matrix was used for further biomineralisation using a simulated body fluid (SBF) solution. The developed composites show better mineralisation

• bioactive glass has a mechanical tensile strength of 67 MPa. In addition, excellent biomineralisation was observed in SBF which shows the ability of bone mineral formation of chitosan nanocomposites [64]. Chitosan and tetraethoxysilane-based aerogels show cell attachment and proliferation of human

Nevertheless, the current mass resolution of the spectrometers allows for several interesting applications in biology, which comprise biomineralisation, microbial corrosion, and interactions between nanoparticles and cells or tissues. Alternative

In nature, silica biomineralisation typically takes place on organic matrices composed of compounds such as chitin and collagen that are preferential sites for nucleation and control the formation of the silica structures [35].

Such a characterisation assay or protocol is even useful for the design of peptides mimicking the biomineralisation process. It would
