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