Formation of self-assembled octadecylsiloxane monolayers on mica and silicon surfaces studied by atomic force microscopy and infrared spectroscopy

Article Abstract:

The effect of the substrate and the specific preparation conditions on the structure of submonolayer films and on the film growth mechanism were studied using two largely different substrates, native silicon and mica. The growth process of self-assembled octadecylsiloxane (ODS) monolayers was also monitored under systematic variation of the water content in the adsorbate solution and age of the adsorbate solution. Results reveal the involvement of both a continuous growth and an island-type growth in the formation of ODS monolayers. Island-type growth is strongly favored on both silicon and mica surfaces with increasing water content or increasing age of the adsorbate solution.

Direct observation of DPPC phase domain motion on mica surfaces under conditions of high relative humidity

Article Abstract:

The submicron liquid condensed and liquid expanded lipid domains in L-alpha-dipalmitoylphosphatidylcholine monolayers move and assemble on mica surfaces at high relative humidity (RH). The activity is done in such a way that the relative areas of the two phases remain constant while the length of the domain perimeter is reduced. The evolution of the film structure is very sensitive to the composition of the subphase used in the film transfer process.
