Upconverting nanoparticles (UCNPs) are a class of recently developed luminescent
biomarkers that–in several aspects–are superior to organic dyes and quantum dots. UCNPs …

The discovery of new fluorescent proteins (FPs) that emit in the far-red part of the spectrum,
where light absorption from tissue is significantly lower than in the visible, offers the …

Autofluorescence is a nuisance in the field of fluorescence imaging and tomography of
exogenous molecular markers in tissue, degrading the quality of the collected data. In this …

For centuries, biological discoveries were based on optical imaging, in particular microscopy
but also several chromophoric assays and photographic approaches. With the recent …
