Claim Text:
1. A metal ion nanocluster having a particle size of 2 to 500 nm, a molecular weight of 3500 to 1000000 Dalton, and a formula of X(OH)aY b Z c M d (H 2 O) e , in which X is a metal cation, Y is a water-soluble salt-forming anion, Z is a water-soluble ligand, M is a turbidity point modifier, a is 0.1 to 20, b is 0 to 9, c is 0.1 to 10, d is 0.1 to 9, and e is 0 to 25, wherein the metal cation is Mg(II), Al(III), Ca(II), Cr(III), Cu(II), Zn(II), Mn (II), Ti(IV), Fe(II/III), Co(II), Ni(II), Bi(III), V(V), La(III), Mo(VI), Sr(II), Zr(IV), or a combination thereof; the turbidity point modifier is a complex-forming polyvalence anion, a carboxylated polyol, a carboxylated polyether, a sulfonated carbohydrate, a sulfonated polyol, a sulfonated polyether, a phospholated carbohydrate, a phospholated polyol, a phospholated polyether, an amino acid, a water-soluble polypeptide, a water-soluble protein, or a combination thereof; and the nanocluster has a turbidity point of 8 or lower.
