The study investigated the nature and molecular organization of synthetic artificial mimic molecules resembling the following tetraether lipids: di-O-hexadecyl-glycero-3-phosphatidyl-glycerol (DHGPG) and bis-4-dodecylphenyl-12- phosphate. These molecules were analyzed using combinations of Langmuir film balance, ellipsometry and atomic force microscopy. Langmuir-Blodgett monolayer film from DHGPG and bis-4-dodecylphenyl-12-phosphate stable on modification solid surface silicon wafers (hydrophilic, hydrophobic and Amino-silanized). The ellipsometry and AFM results showed that the Langmuir-Blodgett monolayer films of DHGPG and bis-4-dodecylphenyl-12-phosphate were present, and the observed film thickness varied from 1.2 - 5.0 nm.
The modification of the solid surface-supported wafer silillon to hydrophilic, hydrophobic, Amino-silanized is very important and causes Langmuir Blodgett monolayer films of DHGPG and bis-4-dodecylphenyl-12-phosphate to become stable on a solid surface wafer silicon. If without surface modification of silicon wafer to hydrophilic or hydrophobic or Amino-silanized, Langmuir Blodgett monolayer film of DHGPG and bis-4-dodecylphenyl-12-phosphate have unstable.
