摘要：
Langmuir-Blodgett films of dimyristoylphosphatidylcholine (DMPC) have been studied on both macroscopic and microscopic scales by atomic force microscopy in the LE-LC coexisting phase (liquid expanded and liquid condensed phase). Macroscopic scale images show that Langmuir-Blodgett films of DMPC have many similar domain structures as observed in fatty acids Langmuir-Blodgett films. In addition, it is observed that some phospholipid molecules crystalize out. A molecularly resolved image was only obtained in LC phase while in the LE phase, no molecularly resolved image was obtained because the films were destroyed by the tip interaction.
