Mesoporous TiO2 synthesis using a semi-hard biological template

Superaerophobic hydrogels for enhanced electrochemical and photoelectrochemical hydrogen production

“…To enable efficient (photo)electrochemical hydrogen production, superaerophobic hydrogels were readily formed on a target electrode by cross-linking the M13 virus. This virus was chosen as the building block for the hydrogels because of its inherent nanofibrillar structure, hydrophilicity (30), and high stability under various conditions (31)(32)(33)(34). At ambient temperature and pressure, the M13 virus readily forms a highly porous hydrogel through a condensation reaction with glutaraldehyde ( Fig.…”

Application of Bacteriophages in Nanotechnology

“…The nanometer virus structure is monodisperse and in the case of some phages, self-assembling [ 96 , 97 ]. Those features, followed by the rapid multiplication of uniform copies with a previously selected or even genetically engineered structure, are ideal for applying phages either as building components or templates/scaffolds for the production of novel bio/nanomaterials [ 98 , 99 , 100 , 101 , 102 ]. The physicochemical properties of individual phages determine the future use of phage-based nanomaterials.…”

“…The second type of technological process exploits the nanometer dimensions of phages to create scaffolds or templates apart from their biological properties. For example, in an example of TiO 2 porous material synthesis, phages are mixed with titanium isopropoxide/ethanol based solution (50% v / v ) and calcinated at 500 °C [ 98 ]. The last type of phage-based materials uses selected phage building components as the empty capsid, structural proteins, receptors, or displayed peptides.…”

“…Hernández-Gordillo et al [ 98 ] presented the application of M13 phages to create porous TiO 2 material. Titanium alkoxide and ethanol were mixed with phage suspensions.…”

TiBALDH as a precursor for biomimetic TiO2 synthesis: stability aspects in aqueous media

“…10,11 Importantly, this technique has the advantage of avoiding organic solvents that can alter the chemical and structural stability of biomolecules. 12 Being titanium oxide a material with interesting properties and technological applications in elds such as pigments industries, (photo)catalysis, 13 energy production and storage, 14,15 among others, its synthesis by biomimetic techniques has been explored. 16 The major research in this eld has used TiO 2 as target, to identify peptide sequences that have affinity to this material and subsequent use as template to guide its biomineralization.…”
