Fluorometric Determination of bisphenol A with β-cyclodextrin

Bisphenol A doubted as endocrine-disruptor. It does not dissolve easily to water, and fluorescence is weak in water. The cycrodextrin which is compound of ring structure, and dissolve to water. The cycrodextrin have internal holl that receive to bisphenol A, and the mixed solution have strog fluorescence. This reaction is peculiar for bisphenol A. When this reaction is used, trace amount of bisphenol A is detected. The detection sensitivity was ppb level, and the solved bisphenol A from baby gadgets
