Degradation of DNA by silicic acid
Mutation Research Letters, 1984S1 nuclease hydrolysis and hydroxyapatite chromatography were used to study the effect of silicic acid on DNA. Native calf thymus DNA was incubated with increasing concentrations of silicic acid (DNA nucleotide/silicic acid molar ratios of 1:0.25, 1:0.5 and 1:1) and subjected to S1 nuclease hydrolysis.

Aqueous Silicic Acid, Silicates and Silicate Complexes
1978The paper aims at giving a brief review of the aqueous chemistry of silicic acid, silicates and silicate complexes. In particular, problems concerning equilibria and structures are discussed. In addition geochemical data of silicon and silicon distribution on the earth crust will be briefly presented.

Derivatives of silicic acids as model compounds for silicates
Physics and Chemistry of Minerals, 1988Silicon-29 chemical shifts of methyl, ethyl, chloro and trimethylsilyl derivatives of silicic acids are compared to those of silicic acid anions found in aqueous solutions. Although the chemical shifts of the silicate anions vary with pH and concentration, a good correlation is obtained for the chloro and alkoxi derivatives.
