摘要：Monolayers of L-α-Dipalmitoylphosphatidylcholine (DPPC) on the air-water interface have been transferred at a middling applied surface-pressure onto the mica substrates using the Langmuir-Blodgett (LB) technique. AFM was applied to observe the formation of morphology of DPPC. Our results show that the Langmuir-Blodgett monolayers of DPPC on mica substrates generate a structured surface with periodic channels and stripes. The LB monolayers obtained at a surface pressure correspond to 20 mN/n. We take into account several explanations to understand the observed surface topological views. On the other hand, a lot of lipids, their Langmuir monolayer and Langmuir-Blodgett monolayer are excellent models of half-layer biological membranes, which can provide closer biological environment. Therefore, using the lipid Langmuir-Blodgett or Langmuir monolayer as prototype, one can simulate further biological environment and make further investigation on biomineralization mechanism of template-controlled.
