Abstract:Biotoxins are a group of significant biogenicactive compounds and become the focus of attention in the fields of public safety and medicine research for their toxicity and bioactivity. New detection methods based on mass spectrometry and biosensors improve the sensitivity, specificity and accuracy of analysis and are playing an increasingly important role. Biotoxin reference materials are the essential material base for assuring the accuracy, comparability and traceability of the quantitative results, so many countries are developing biotoxin reference materials in urgent need. The current progress on the detection methods and reference materials of biotoxins in recent years are reviewed in this article.
