Solid-solid reaction preparation for nanoparticles of bioinorganic complex of bismuth and serine at room temperature

Nanoparticles of the bioinorganic complex of bismuth and serine can be prepared very easily by a room temperature solid-solid reaction with the raw materials of bismuth triiodide and serine. The complex is characterized by elemental analysis, X-ray powder diffraction and transmission electron micrograph. The characterizations indicate that the composition of the complex is Bi[I(HOCH2CHNH2COO)](1.5). The crystal structure of the complex belongs to orthorhombic system with the lattice parameters: a = 0.8355 am, b = 1.8688 am and c = 2.2511 am. The average diameter of the bioinorganic complex nanoparticles is about 40 nm.
