Mutagenesis study of a Bacteriophytochrome - insights for the development of labels for optical imaging.

The paper studies a BphP from Rhizobium etli to identify variants suitable for optical imaging, including a bright far-red-shifted BphP and a photoswitching BphP for background suppression in vivo.

A fluorescent biosensor for the visualization of agmatine

The paper develops a fluorescent biosensor (AGMsen) to visualize agmatine dynamics in cells, demonstrating its functionality across neuronal cultures.

Non-invasive optoacoustic imaging visualizes exercise-induced dermal revascularization in obese mice

The paper uses optoacoustic imaging to monitor microvascular changes in obese mice during exercise, showing improved vascular density and oxygenation in adipose tissues.

Macroscopic label-free biomedical imaging withshortwave infrared Raman scattering

This paper introduces a shortwave infrared Raman imaging technique that enables label-free, high-contrast visualization of tissue composition and pathology without contrast agents.

Ligand promiscuity in the tryptophan repressor - from structural understanding towards rational design

The paper investigates ligand promiscuity in the tryptophan repressor TrpR, elucidates structural and thermodynamic data, and demonstrates rational design of ligand specificity.
