Spectroscopy on biomolecules

Research topic: Spectroscopy on biomolecules


The group of Prof. Janne Ihalainen (JYU/NSC) started at the division of Cell and Molecular Biology in January 2009. The research interests of the group lay at the intersection of biology, chemistry and physics and it develops (micro)spectroscopic tools for characterization of biomolecules. The experimental approaches used in the studies are for example time-resolved fluorescence, transient absorption (VIS–VIS and VIS–MIR), and Raman techniques.
