Assignee: NH THERAGUIX
Field: Pharmaceuticals (Chemistry)
Classification: CPC A  B | IPC A  B

Claim 2:
3. The nanovector according to claim 1, wherein the nanoparticle is of formula (I) below:

Sin[O]m[OH]o[Ch1]a[Ch2]b[Ch3]c[My+]d[Dz+]e[Gf]f  (I)

in which:
n is between 20 and 5000,
m is greater than n and less than 4 n,
o is between 0 and 2 n,
Ch1, Ch2 and Ch3 are chelating agents, which may be identical or different, bonded to the Si atoms of the polysiloxanes by an Si—C covalent bond; a, b and c are integers between 0 and n and a+b+c is less than or equal to n,
My+ and Dz+ are metal cations, which may be identical to or different from one another, with y and z=1 to 6; d and e are integers between 0 and a+b+c, and d+e is less than or equal to a+b+c,
Gf is a targeting graft, which may be identical to or different from one another, each bonded to the Si by an Si—C bond and resulting from the grafting of a targeting molecule allowing the targeting of the nanoparticle to biological tissues of interest, and f is an integer between 0 and n.
