(A) Schematic diagram of the integrated scanning electrochemical cell microspectroscopy (iSECCMS) platform that combines scanning electrochemical cell microscopy (SECCM) with fluorescence spectroscopy. (B) The capillary tip of the iSECCMS platform can be moved in the XYZ directions, which enables the operator to accurately position the measurement location. (C) Photograph of the iSECCMS platform. (D) Microscope image of a pulled theta capillary used in the platform. (E) The focal region of light from the inverted microscope placed under the working electrode. (F) The theta capillary mounted with a shear-force assembly to control the position of the tip in the Z-direction while landing it on the electrode surface during measurements.
