Adsorption of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine on Au(111) and HOPG
Kocábová, Jana ; Sokolová, Romana
Atomic force microscopy (AFM) was used to study the formation of layers of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) on Au(111) and highly oriented pyrolytic graphite (HOPG) in microscopic level. Both substrates were found to support the DPPC layers. The nanoshaving technique was applied to determine the layer thickness. In addition, the influence of deionized water on the DPPC ordering at the substrates was studied by ex-situ and in-situ AFM intermittent contact mode measurements.
