Influence of DNA, Alginate, Lysozyme and Bovine Serum Albumin on Sodium Silicate Condensation

Abstract

The interaction of DNA, alginate, Lysozyme and Bovine Serum Albumin with diluted solutions of sodium silicate was studied using the molybdosilicate method. DNA and alginate showed very weak interactions with silica precursors whereas both proteins were able to form silica gels. Both electrostatic interactions and hydrogen bonds are suggested to arise between peptide chain and polysilicates, bringing new information on the nature of inorganic and bio- organic species involved in the natural biosilicification processes.
