以α，ω-二羧基封端的聚乙二醇为表面封端分子，通过Fe（acac）（3）在2-吡咯烷酮中的热分解反应，一锅法制备了具有生物相容性的表面活性部分的磁铁矿纳米晶。磁铁矿纳米晶与9-氨基吖啶的成功结合一方面证明了PEG结合在粒子表面的游离羧基的存在，另一方面也可能导致新型磁光材料以及磁药物的产生。(c)2007爱思唯尔公司All rights reserved.
By one pot reaction, biocompatible magnetite nanocrystals with surface reactive moieties were prepared through the thermal decomposition of Fe(acac)(3) in 2-pyrrolidone using alpha, omega-dicarboxyl-terminated poly(ethylene glycol) as surface capping molecule. The successful conjugation between the magnetite nanocrystals and 9-amino acridine on the one hand demonstrates the existence of free carboxylic groups from PEG binding on the particle surface, on the other hand may also lead to a new type of magneto-optical materials as well as magneto-drugs.
