我们最近开发了致密的、水溶性的两性离子多巴胺磺酸盐(ZDS)配体包裹的超顺磁性氧化铁纳米颗粒(SPIONS),用于各种生物医学应用。ZDS包被的SPION的主要特征是流体力学直径小,与胎牛血清的非特异性相互作用低,有机会进行特定标记,以及在时间、pH和盐度方面的稳定性。我们在这里报告了ZDS包裹的SPION的磁性特征,以及它们在体外和体内分别与HeLa细胞和小鼠的非特异性相互作用的性能。ZDS包覆的SPION保持了合成的SPION的超顺磁性和饱和磁化强度,其饱和磁化强度为74emu/g[Fe]。此外,ZDS包裹的SPIOns在体外仅对HeLa癌细胞有少量的非特异性摄取,在小鼠体内对血清蛋白的非特异性结合较低。
We have recently developed compact and water-soluble zwitterionic dopamine sulfonate (ZDS) ligand coated superparamagnetic iron oxide nanoparticles (SPIONs) for use in various biomedical applications. The defining characteristics of ZDS-coated SPIONs are small hydrodynamic diameters, low non-specific interactions with fetal bovine serum, the opportunity for specific labeling, and stability with respect to time, pH, and salinity. We report here on the magnetic characterization of ZDS-coated SPIONs and their in vitro and in vivo performance relative to non-specific interactions with HeLa cells and in mice, respectively. ZDS-coated SPIONs retained the superparamagnetism and saturation magnetization (Ms) of as-synthesized hydrophobic SPIONs, with Ms=74 emu/g [Fe]. Moreover, ZDS-coated SPIONs showed only small non-specific uptake into HeLa cancer cells in vitro and low non-specific binding to serum proteins in vivo in mice.
