Ratiometric fluorescence detection of aflatoxin B1 in food samples using metal-organic framework confined within mesoporous silica.
Aflatoxin B1 (AFB1) is a highly toxic and carcinogenic mycotoxin that poses significant threats to food safety and human health. A composite material, formed by confining Zr-based metal-organic framework (Zr-LMOF) within aminated mesoporous silica (ASBA-15) and integrating with Ru(bpy)32+, provides a stable and sensiti...
