Corneodesmosin, a protein known to be present in the stratum corneum (SC), plays an important role in its physical integrity. Here, a specific antibody to corneodesmosin was tethered via a flexible linker to an atomic force microscopy tip, and the interaction forces between this tip and the surface of the SC were successfully measured. Using the recently developed technique of simultaneous topography and recognition imaging, we were able to map the distribution of corneodesmosin on the surface of the SC at the nanoscale.
