Submonolayer of DPDI
Submonolayer of DPDI (4,9-diaminoperylene-quinone-3,10-diimine, a Perylen derivate) on Cu(111) surface. Under the influence of heat (300°C) a hexagonal network of Perylen-derivatives (DPDI) is formed. The emerging holes can be used to catch other molecules - here C₆₀-molecules. (Picture: Meike Stöhr)

Asymmetric unit membrane (AUM)
Imaging of the native asymmetric unit membrane (AUM) by contact mode scanning force microscopy (CMSFM) SFM reconstruction based on averaging over 100 plaque particles each for the luminal and cytoplasmic face of the asymmetric unit membrane (AUM) of urine bladder epithelium. The luminal side (upper left half in orange) of particles protrudes about 6.5nm relative to the lipid bilayer and the cytoplasmic face (lower right half in blue) only 0.5nm, hence the name "asymmetric unit membrane". Averages are based on contact mode SFM imaging in buffer solution. These particles form 2D crystalline plaques in situ. Center to center distance: 16nm
