title: Green upconversion nanocrystals for DNA detection.
abstract: By combining magnetic-field-assisted bioseparation and concentration technology with magnetite nanoparticles, novel green upconversion (UC) fluorescence nanocrystals (NaYF4:Yb3+/Er3+) have been applied to the sensitive detection of DNA.
