| 摘要 |
The present invention relates to Titanium, Niobium or Tantalum oxide-based compounds containing chemically bound functional multivalent polyamines for surface binding (absorption) of nucleic acids. The chemical composition of the new metallates is as follows: Formula (1) or Formula (2) or Formula (3) wherein k, m, q, w, x, y, z are coefficients of at most 1 n is an integer, wherein 0 ≤ n ≤ 10 A is at least one cation of valence 1 to 3 M is at least one metal having valence 1 to 7 P is a chemically bounded polyamine or polyamine cation. |
