| 英文摘要 | A novel route has been developed to prepared beta-cyclodextrin (beta-cd) functionalized magnetic nanoparticles (mnps). the mnps were first modified with monotosyl-poly(ethylene glycol) (peg) silane and then tosyl units were displaced by amino-beta-cd through the nucleophilic substitution reaction. the monotosyl-peg silane was synthesized by modifying a peg diol to form the corresponding monotosyl-peg, followed by a reaction with 3-isocyanatopropyltriethoxysilane (ipts). the success of the synthesis of the monotosyl-peg silane was confirmed with (1)h nmr and fourier transform infrared (ftir) spectroscopy. the analysis of ftir spectroscopy and x-ray photoelectron spectroscopy (xps) confirmed the immobilization of beta-cd onto mnps. transmission electron microscopy (tem) indicated that the beta-cd functionalized mnps were mostly present as individual nonclustered units in water. the number of beta-cd molecules immobilized on each mnp was about 240 according to the thermogravimetric analysis (tga) results. the as-prepared beta-cd functionalized mnps were used to detect dopamine with the assistance of a magnet. |
