Overview

Experimental study demonstrates dual-mode luminescent colloidal spheres assembled from rare-earth fluoride nanocrystals, suggesting strong utility for multiplexed bioassays.

Key Points

  • Fabricate dual-mode luminescent colloidal spheres using monodisperse rare-earth fluoride nanocrystals for application in sensitive and multiplexed bioassays.
  • Synthesized uniform monodisperse rare-earth fluoride nanocrystals to serve as modular building blocks.
  • Assembled the nanocrystals into dual-unit colloidal spheres engineered with distinct luminescent domains.
  • Successfully produced dual-mode colloidal spheres displaying down-converting luminescence under ultraviolet light and up-converting luminescence under 980 nm laser excitation.
  • Established a dual-responsive luminescent architecture capable of supporting multiplexed, high-sensitivity biological detection.
