- •
A upconversion ratiometric fluorescence and colorimetric method for UA was designed.
- •
The platform to UA was based on upconversion UCNPs and ZnFe2O4 magnetic beads.
- •
The FL and UV detection limits reached 2.86 μM and 5.79 μM, respectively.
- •
The proposed method has been successfully applied to the analysis of UA in serum.
