Evanescent wave cavity ring-down spectroscopy (EW-CRDS) is a surface sensitive technique, which allows optical absorption measurements at interfaces with good time resolution. In EW-CRDS, a pulsed or modulated laser beam is coupled into an optical ca

The electrochemical control of the redox reactions of vitamin B12 and derivatives thereof plays an important role for the in vivo investigations of the B12 dependent biological transformations. While most of these studies were performed in solution,

We describe highly localized electrochemical measurements and imaging using a simple, mobile theta pipet cell. Each channel (diameter500 nm) of a tapered theta pipet is filled with electrolyte solution and a Ag/AgCl electrode, between which a bias is
