Silica-core quantum dot fluorescent probe

90-day stability

This probe uses SiO₂ nanospheres as the core, with CdSe/ZnS quantum dots self-assembled via a PEI interlayer and conjugated to anti-DON monoclonal antibodies, enabling rapid fluorescence-based quantitative detection of vomitoxin in cereals.
