Understanding FRET in Upconversion Nanoparticle Nucleic Acid Biosensors.
Nano letters (Print), 2023Upconversion nanoparticles (UCNPs) have been frequently applied in Förster resonance energy transfer (FRET) bioanalysis. However, the understanding of how surface coatings, bioconjugation, and dye-surface distance influence FRET biosensing performance ...

Responsive Sensors of Upconversion Nanoparticles
ACS Sensors, 2021Upconversion nanoparticles are a class of luminescent materials that convert longer-wavelength near-infrared photons into visible and ultraviolet emissions. They can respond to various external stimuli, which underpins many opportunities for developing the next generation of sensing technologies.
