Abstract

The structure of the Langmuir purple membrane (PM) monolayer was studied by scanning tunneling microscopy (STM). The topography of both the external and cytoplasmic sides of the monolayer was investigated. The thickness of the PM monolayer was determined to be about 4 nm. PM films include specific oval 'crater'-like structures of 50-60 nm in diameter.
