Drug-target interactions
Detailed insights into molecular interactions of the antimalarial artesunate with its target-structure β-hematin are of outmost importance for the tailored design of future efficient antimalarials. These findings were derived by a novel combination of resonance Raman excitation, two-dimensional correlation analysis, and density functional theory calculations of β-hematin and its complexes.

High-throughput spectroscopy
Parallelized multifocal Raman difference spectroscopy reveals even the smallest spectral differences that occur due to weak interactions between substances. The new setup enables the investigation of subtle changes due to biochemically important molecular interactions and opens new avenues to perform drug binding assays and highly parallelized monitoring of chemical reactions.

UV Raman spectroscopy
Deep UV resonance Raman spectroscopic analysis provides high sensitivity for the quantification of the antimalarial ferroquine (FQ) in the food vacuole of a parasitized erythrocyte and gives insights in the excellent permeation behavior through parasitophorous membranes which result in a strong enrichment at the site of action inside Plasmodium falciparum.
