中文摘要：
近年来，二氧化硅纳米管因具有均匀、敞开的纳米孔道结构及用基质本身优良的化学和机械稳定性等优点而在细胞标记、药物运输、DNA转染和选择性分离等方面显示出广阔的应用前景．其中，磁性二氧化硅纳米管不仅具有纳米管的所有特征，而且还可以在外加磁场的作用下定向移动，更有利于靶向标记、催化剂载体和分离富集等应用．然而，目前对于磁性纳米管的研究还处于初步阶段．
英文摘要：
In this study, we report the preparation and application of the AlC4 Pc-magnetic silica nanotubes （AlC4 Pc-MSNs） , which was synthesized via alumina template membrane method. The synthesized outer-NH2- magnetic silica nanotubes（outer-NH2-MSNs） were characterized by TEM, SEM, EDS and SQUID. Besides these, UV-Vis absorption spectra and fluorescence spectra were also recorded, which further indicate that the AlC4Pc-MSNs have the similar features with free AlC4Pc. The AlC4Pc-MSNs not only have all the advantages of silica nanotubes, but also can be easily separated from the solution by external magnetic field. On the basis of the merits mentioned above, AlC4Pc-MSNs was used for the detection of pH value. Our work herein reveals that the outer-NH2-MSNs will be a promising platform for the applications of the targeting drug delivery, DNA transfection, selective separation, catalyst carriers and so on.
