Abstract: Anew synthetical method for nanomaterials was developed, and the semiconductor nanocrystalline CdSwas fabricated through controlling of the living biomembrane in bean sprouts. The results indicated that approximately spherical CdSparticles about 5.1 nm, which has a cubic zinc-blende structure with a cell constant a =0.5818 nm, could be formed after the bean sprouts were successively soaked in 0.1 mol·L-1 Na2S and 0.1 mol·L-1 CdCl2 for 24 h. In addition, the tentative research for the reaction mechanism has been carried out.

Key words: Biomembrane method, Cadmium sulfide, Nanocrystallites
