A probing combination: Integration of amperometric microbiosensors into combined tips for AFM–scanning electrochemical microscopy allows specific detection of molecular species independent of the AFM measurement, but correlated in space and time with the surface morphology. The applicability of this multidimensional approach is demonstrated by imaging glucose transport across porous membranes at the nanoscale (see picture).
