G. Dobrescu et al., FRACTAL ANALYSIS OF ADHESION ATOMIC-FORCE MICROSCOPY APPLIED TO LIPIDMONOLAYERS, Revue roumaine de chimie, 43(5), 1998, pp. 417-424
Adhesion atomic force microscopy (AFM) can be used to characterize the
surface chemical composition of lipid monolayers. Analyzing adhesion
AFM images of dimyristoylphosphatidylethanolamine (DMPE) monolayers on
mica, we demonstrated that liquid-condensed domains are fractals. Fra
ctal dimension calculation using adhesion atomic force microscopy imag
es of lipid monolayers shows that this method introduces artifacts tha
t must be carefully eliminated.
