Abstract: Utilizing biomineralization mechanism of eggshell membrane and its control over ions transfer, three kinds of nanocrystals of copper group sulphides were synthesized with eggshell membrane as a template. This indicates the feasibility of synthesizing nanomaterials with eggshell membrane and provides a novel template method for the formation of inorganic nanomaterials. The results show that the average diameters of CuS, Ag2S and Au2S3 nanocrystals obtained from the experiment were 30, 24 and 22 nm, respectively; the three kinds of nanocrystals all have some special properties such as fluorescence, none absorb peak in FT-IR, and they also have some new absorb peaks in UV-V is while the bulk materials haven't.
Key words: nanocrystals; copper group sulphide; biomimetic synthesis; template; eggshell membrane
