“…The composites obtained by ‘filling’ these voids of protein crystals as biotemplates have potential in providing nanostructured, 3D, highly accurate arrays of hybrid materials for applications in fields such as electronic devices (for a review of potential applications, see [72]) and spectroscopy (for related reviews, see [73,74,75,76]).…”

Purified proteins offer a homogeneous population of biological nanoparticles, equipped in many cases with specific binding sites enabling the directed self-assembly of envisaged one-, twoor three-dimensional arrays. These arrays may serve as nanoscale biotemplates for the preparation of novel functional composite materials, which exhibit potential applications, especially in the fields of nanoelectronics and optical devices. This review provides an overview of the field of protein-mediated biotemplating, focussing on achievements made throughout the past decade. It is comprised of seven sections designed according to the size and configuration of the protein-made biotemplate. Each section describes the design and size of the biotemplate, the resulting hybrid structures, the fabrication methodology, the analytical tools employed for the structural analysis of the hybrids obtained, and, finally, their claimed/intended applications and a feasibility demonstration (whenever available). In conclusion, a short assessment of the overall status of the achievements already made vs. the future challenges of this field is provided.

“…We proposed the fabrication of nanodevices using biomolecules with peptide aptamers (named Bio Nano Process). − The Bio Nano Process employs cage-shaped proteins, such as ferritin (Φ 12 nm) and DNA binding protein from starved cells (Dps, Φ 9.5 nm). Various kinds of uniform Φ 7 or Φ 4.5 nm nanoparticles were synthesized in their cavities with one-pot biomineralization reactions.…”

Using the M13 phage display method, 236 amino acid sequences (peptide aptamers) that could specifically adsorb to CNTs were selected. These peptide aptamers had abundant hydrophobic amino acids and evenly dispersed charged amino acids. The hydrophobic amino acids were postulated to contribute to CNT adsorption, while the charged amino acids contribute to their aqueous solubility. The frequency of proline amino acids, which causes the amino acid main chain bending, was slightly higher than in nature, suggesting that some conformational constraint might be required. Four peptide aptamers with a high frequency of occurrence in the selected sequences were further studied. Hydrophobicity scores were periodic along the amino acid sequence. 3D structure predictions by PEP-FOLD3 indicated that these aptamers would take a helical structure with hydrophobic amino acid residues on one side, suggesting that the aptamers bind hydrophobically to the CNT. The adsorption of these four aptamers to the carbon electrode was confirmed by electrochemical impedance spectroscopy, which demonstrated the effectiveness of the phage display method. At the same time, it was shown that even for selected peptides, the adsorption performance varied, and verification was needed.
