Abstract:

Lanthanide doped nanoparticles offer numerous advantageous spectroscopic properties and features, which make them particularly useful and promising to be applied for biosensing and bioimaging in the field of biology, biotechnology, technology and biomedical sciences . In the course of this lecture, fundamental properties of these luminescent labels will be described in relation the requirements imposed by these biomedical applications. Various types of luminescence and energy transfer processes will be discussed to enable deeper understanding of the optical transitions leading to efficient anti-Stokes (ETU, ESA, PA, CR etc.) emission, which will be confronted with the optical properties of biological samples (absorption, scattering, autofluorescence). Moreover, specific requirements and methods, such as surface passivation and core-shell nanomaterials, aiming to circumvent existing drawbacks of using nanoparticles in biological fluids will be described. Finally, an overview of such potential applications will be discussed, including luminescent labelling, sensing in biology (FRET) and physics (temperature), optical cooling, imaging and super-resolution imaging.
