Lanthanide-doped upconverting nanoparticles (UCNPs) are one of the most promising materials for the food safety detestion due to their unique chemical and optical properties.It was found that the UCNPs had a favorable effect on brucellastreptococcus and escherichia coli. To enhanced its application in the field of food safety detection,the synthesis technology and surface modification methods should be improvemented.Here,we successfully synthesized the UCNPs with different coating agent by the hydrothermal synthesis method and discussed the different methods to modify the surface of the UCNPs,which can enable it better to be applicated in the field of the food safety detection.
