Poly[2-(methacryloyloxy)ethylphosphorylcholine]-coated SPIONs were prepared through ATRP and amidation coupling reactions. The coated SPIONs exhibited high stability and re-dispersability in phosphate buffered saline and uptake in a stem cell line, with high T(2) relaxivity.
通过原子转移自由基聚合(ATRP)和酰胺化偶联反应制备了聚[2-(甲基丙烯酰氧)乙基磷酸胆碱]-包覆的 SPIONs。包覆的 SPIONs 在磷酸盐缓冲盐水中表现出高稳定性和再分散性,并在干细胞系中摄取,具有高 T2 弛豫率。
