Recent advances in biomolecular vibrational spectroelectrochemistry

Spectroelectrochemical studies of biomolecules have gained attraction due to the breadth of information that can be derived from combined in situ bioelectrochemistry-spectroelectrochemistry experiments. This current opinion article provides a comprehensive overview focusing on surface-enhanced IR and Raman spectroscopic techniques applied in bioelectrochemical studies published within the past 3 years. Next to fundamental studies also sensing applications will be discussed taking advantage of advanced spectroelectrochemical techniques.
