[Application of carboxylated polystyrene latex particles in the detection of aflatoxin B1].
OBJECTIVE
To study on rapied detection technique of aflatoxin B1.


METHODS
Carboxylated polystyrene latex particles(CPLP) were prepared by soap-free polymerization using styrene and alpha-methyl crylic acid. The CPLP were sensitized with aflatoxin B1 oxime-BSA for the detection of aflatoxin B1.


RESULTS
The minimum detect limits of sensitized latex were 5 ng/ml,


CONCLUSIONS
The sensitized latex could applied to detect qualitative and half-quantitative aflatoxin B1 in fieldwork. The technique maybe minim, simpleness, rapidness and specificity.
