Biosilica and bioinspired silica studied by solid-state NMR

Review on a novel biosilica source for production of advanced silica‐based materials: Wheat husk

“…Silica is the third most common occurring biogenic mineral, after calcium carbonate and calcium phosphate . Silica is a frequently used material in many application areas including bioactive implants, catalysis, drug delivery systems, food additives, nanoelectronics, and sensory systems .…”

“…Silica is the third most common occurring biogenic mineral, after calcium carbonate and calcium phosphate. 54 Silica is a frequently used material in many application areas including bioactive implants, 55,56 catalysis, 57 drug delivery systems, 58 food additives, 59 nanoelectronics, 60 and sensory systems. 61 The silica can be named as biosilica when it is found in natural living sources such as plants like horsetail, bagasse, corn, rice, and wheat, and also in aquatic living beings like diatoms, radiolaria, and siliceous sponges.…”

NMR of Macromolecular Assemblies and Machines at 1 GHz and Beyond: New Transformative Opportunities for Molecular Structural Biology

“…For these studies, high magnetic fields (≥ 800 MHz) were valuable to overcome challenges associated with quadrupolar nuclei. Biosilica materials, such as enzymes encapsulated in or immobilized on an inorganic matrix of silica, are of great interest for their applications in biotechnology and chemical catalysis (194, 195). Catalytic activity of biosilica-associated enzymes requires conservation of active site structure upon association with the silica network.…”

Efficient enzyme encapsulation inside sol-gel silica sheets prepared by poly-L-lysine as a catalyst

“…In this field, the inorganic materials that use biomineralization approaches have become an important area of the research [20][21][22][23][24][25]. One extensively study is the biomineralization of highly ordered biosilica from alkoxysilane such as tetramethoxysilane (TMOS) and tetraethoxysilane (TEOS) using biomolecules (e.g., peptides, proteins, and nucleic acids); this system offers precise control the nanostructure of the obtained inorganic material [26][27][28][29][30]. In addition, polyamines and polypeptides (like poly-L -lysine) can catalyze silicic acid deposition [31][32][33][34][35].…”
