摘　　要：Oligo-（lysine） n （n = 1-4） containing different numbers of lysine residues was used to induce the condensation of silicic acid to form silica particles in neutral silicate solution. It was found that the condensation rate and the formation of silica particles are dependent on the number of lysine residues in an oligo-lysine. Oligo-lysine with more lysine residues can link more silicic acid together to form a matrix that promotes the effective aggregation of the condensed silica pieces to form large silica particles.Oligo-（lysine） n （n = 1-4） containing different numbers of lysine residues was used to induce the condensation of silicic acid to form silica particles in neutral silicate solution.
