Upconversion fluorescent nanomaterials for biodetection and bioimaging

Submission status
Closed
Traditional fluorophores including fluorescent dyes/proteins and quantum dots are based on ‘downconversion fluorescence’, converting high energy photons to low energy photons. Upconversion nanoparticles (UCNPs) present a new technology for sensitive imaging and detection in various fields. Unlike traditional fluorophores, UCNPs emit detectable high energy fluorescence in the UV/visible/NIR range upon irradiation with NIR light based on a process termed ‘upconversion’. They can be used for ultrasensitive interference-free biodetection/imaging because most biomolecules do not have this upconversion property. The major advantages of this approach include but are not limited to: multi-color, low background autofluorescence, single wavelength excitation, good photostability, and spectral unmixing. This topical collection is focused on the synthesis of UCNPs with new compositions/structures, tunable fluorescence emission and improved fluorescence intensity, and use of these nanoparticles for biodetection and bioimaging, both in-vitro and in-vivo.
