摘要: Abstract Deoxynivalenol, a secondary metabolite of Fusarium graminearum, is suspected carcinogen. It has great threat to people's health. A sensitive determination method for deoxynivalenol necessary satisfy food safety requirement. In this study, traditional chemiluminescent enzyme immunoassay (CLEIA) was modified by replacing the microplate with magnetic nanoparticle as immobile phase. The limit detection novel CLEIA low 0.032 ng/mL. linear range 0.1–20 ng/mL. within-run and between-run precisions were 2.1%–4.7% 5.4%–10.0%, respectively. And showed good specificity. Therefore, it could be concluded that nanoparticles phase improve sensitivity precision through merits microparticle separation. This significant work safety.
