“…Chemical methods are often used for obtaining nanostructured oxides. Since nature always inspired scientists with its biostructures with optimized shape and patterns, methods using natural biotemplates for obtaining nanostructured oxides have been described in the literature [1]. ESMs are organic interwoven fibers with a few micrometers in diameter, mainly composed by proteins which determine their inorganic surface structure.…”

Alginate hydrogel (AH) has intrinsic physical and biological limitations that hinder its broader application in tissue engineering. We hypothesized that the inclusion of nanofibers in the hydrogel and the use of a biotemplate that mimics nature would enhance the translational potential of alginate hydrogels. In this study, we have shown a method to obtain nano-/microfibers of titanium (nfTD) and hydroxyapatite (nfHY) using cotton as a biotemplate. These fibers were incorporated in the alginate hydrogel and the mechanical characteristics and biological response to these reinforced materials were evaluated. We observed that these nanofibers resembled the structure of natural collagen and did not mediate cell toxicity. The incorporation of nfTD or nfHY to the AH has not increased the viscosity of the hydrogel. Therefore, this is a feasible method to produce a scaffold with improved physical characteristics, while at the same time generating an enhanced environment for cell adhesion and proliferation.

“…Protein crystals possess a three-dimensional ordered arrangement of protein molecules. 93 Cohen et al 94 dissolved CLPCs in aqueous ethylene glycol, induced polymerisation by the addition of ammonium persulfate, and then retrieved the crystals. Cvetkovic et al 91 investigated the transport of uorescein in lysozyme crystals by confocal laser scanning microscopy and found that the diffusion rate was highly related to the crystal structure.…”

Cross-linked protein crystal technology, as either a protein stabilisation or enzyme immobilisation method, has garnered more attention recently. This method not only can retain the original activity of the protein molecule but can also significantly enhance the crystals' mechanical and chemical stability. This review presents the preparation and mechanism of cross-linked protein crystals using glutaraldehyde. The mechanical, chemical and thermal properties of the cross-linked protein crystals are also reviewed in detail. In addition, this paper summarises the applications of cross-linked protein crystals in the fields of materials science, biosensors, chromatographic analysis, oral delivery and protein crystal quality improvement. Finally, the limitations and perspectives on cross-linked protein crystals are presented.Crystallisation is a well-known approach to obtain highly puri-ed proteins. During crystallisation, protein molecules can be Fig. 2 A schematic diagram of the polymerisation of glutaraldehyde. 21This journal is
