(lysine, arginine or histidine). This reflects the design of silaffin, a natural silica-mineralizing protein rich in lysine and arginine residues [58][88]. Therefore, we speculated that bare TMV–Lys templates could also support the formation of silica shells in TEOS solution. The effect could be greater

present experiments which quantify the additivity, and potential cooperativity of long chain polyamines (LCPAs) and cationic peptides in the silicification process.

. Biosilicification however, relies on the sharp differentiation between soluble and entrapped molecules, a sophisticated form of chemoselective silicification. Currently accepted models are the LCPA–phosphate model [4] and the silaffin-matrix hypothesis [5]. Both formulate varying concentrations of soluble
analyzed to what extent the mineralisation process and the morphology of the precipitate depends on the number of propyleneimino repeating units [11], the type of KXXK-boxes in silaffin proteins (K = Lys, X = other amino acid) [12], or the number of POG tripeptide repeating units in collagens [13].
