Title:

COLLOIDAL CRYSTAL AND METHOD AND DEVICE FOR MANUFACTURING COLLOIDAL CRYSTAL GEL

Document Type and Number:

WIPO Patent Application WO/2005/012960

Kind Code:

A1

Abstract:

[PROBLEMS] To solve a problem in a conventional colloidal crystal manufacturing means wherein considerable technique is required for obtaining colloidal crystals and its manufacture depends largely on the technique of a manufacturer by establishing a manufacturing means capable of producing the colloidal crystals with excellent reproducibility to apply and expand the use of the colloidal crystals in various fields in the future. [MEANS FOR SOLVING RPOBLEMS] Gas compressed by a compressor (1) is controlled by a gas pulse control device (3) to generate compressed gas pulses, the gas pulses are led into a colloidal crystal manufacturing container (6) with a flat plate-like capillary part through a tube (4), and the motions of flow and its abrupt stop are given to a colloidal solution in the flat plate-like capillary by using as a drive force, a pressure variation given by the pulses. Thus, the colloidal crystals with excellent single crystallinity can be formed.
