The ion channels formed by gramicidin A molecules embedded in a Langmuir-Blodgett film have been visualized by scanning tunneling microscopy at atmospheric pressure. The film was a bilayer of dipalmitoyllecithin molecules on a graphite surface. The results of the study agree with existing molecular models.
