| 摘 要： | 通过荧光光谱法研究了稀土元素Ｃｅ３＋与二棕榈酰磷脂酰胆碱（ＤＰＰＣ）脂质体的相互作用，结果表明，Ｃｅ３＋－ＤＰＰＣ体系的激发波长在２４７ｎｍ，２９４ｎｍ，发射波长在３４４ｎｍ，与水合Ｃｅ３＋的荧光光谱完全不同。这表明Ｃｅ３＋与ＤＰＰＣ形成了复合物，该复合物的荧光光谱同Ｃｅ３＋－ＤＨＰ复合物的荧光光谱一致。可以认为Ｃｅ３＋与ＤＰＰＣ分子上的磷酸基团相作用。

| Abstract: | The interaction of Ce3 and dipalmitoylphosphatidylcholine (DPPC ) liposome was studied by fluorescence spectra. It was different from the fluorescence spectrum of Ce3 -H2O complex,the excitation wavelengths of Ce3 -DPPC system were observed at 247nm and 294nm, the emission wavelength at 344nm. It indicated the formation of Ce3 -DPPC complex. the observed spectra have the characteristics of the fluorescence spectrum of Ce3 -DHP complex. It is reasonable to suppose that Ce3 is bound to the phosphate group of the DPPC molecule. |
