Interactions of Amino-Containing Peptides with Sodium Silicate and Colloidal Silica: A Biomimetic Approach of Silicification

Coradin, Thibaud, Durupthy, Olivier, Livage, Jacques·2002·Langmuir

Abstract

The influence of poly(lysine) and poly(arginine) on silicate solutions and silica sols has been investigated. In both cases, solid formation could be observed that appeared to depend on the polymer chain length. Polyelectrolytes induced gelation of diluted sodium silicate solutions. Studies of the silicic acid content using the colorimetric molybdosilicate method suggested that polymers act as gelating agents of silica oligomers via electrostatic interactions that favor condensation. In the case of silica sols, quasi-elastic light scattering measurements indicate that particles are first adsorbed on the polymer chain to form aggregates that then flocculate in the presence of additional peptides. Structural characterizations of the solids obtained in both cases were consistent with the proposed models. These results are discussed in the frame of biogenic silica formation at the protein/silica interface.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
