This study investigated the stability behaviour of molecular monolayer symmetric chemically modified tetraether lipids caldarchaeol-PO₄ on the amino-silanised silicon wafer using Langmuir-Blodgett films, Self Assembling Monolayers (SAMs), ellipsometry, and atomic force microscopy (AFM). The monolayers of caldarchaeol-PO₄ were stable on the solid surface amino-silanised silicon wafer. The organizations of molecular monolayers caldarchaeol-PO₄ by Langmuir-Blodgett method and SAMs have been analyzed. The surface of pressure in Langmuir-Blodgett processing is carried out monolayers caldarchaeol-PO₄ more flat island inhomogeneous. Another method of monolayers caldarchaeol-PO₄ by SAMs is showed a large flat domain. Monolayers caldarchaeol-PO₄ by Langmuir-Blodgett method seems to be stable and chemically resistant after washing with organic solvent and an additional treatment ultrasonification with various thickness lipids arround 2 nm to 6 nm. Conversely, monolayer caldarchaeol-PO₄ by SAMs appears fewer than monolayers caldarchaeol-PO₄ by Langmuir-Blodgett method, the thickness of various from 1 nm to 3 nm.
