Chemical Microscopy

The localization and characterization of molecular structures in various geological and biological systems plays an important role in all areas of environmental science.

Chemical microscopy combines high-resolution emission spectra with Abbe-limited spatial resolution and is used for studies of inhomogeneous samples at the (sub-)micronscale. The spatial distinction of multiple Eu(III) coordination sites allows for a comprehensive understanding of environmental samples and highlights the applicability of Eu(III) as a molecular probe in medicine and biology.

For this purpose, the sample is excited with a suitable laser through the microscope's optics and the emission is recorded using a high-resolution detector. The microscopy system used (HORIBA LabRAM system) thus correlatively couples optical microscopy with luminescence and Raman spectroscopy.
