一般描述
右旋糖酐是一种D-葡糖基均一多糖，通过α-1,2、α-1,3和α-1,4连接（相应地分为A、B和C组）与不同分支有a-1,6糖苷键连接。可由蔗糖经无细胞滤液合成。
葡聚糖是分子量≥1,000道尔顿的多糖，有一条α-D-吡喃葡萄糖基重复单元连接的线型主链。葡聚糖是细菌胞外多糖。它们是由肠膜明串珠菌和短乳杆菌通过蔗糖合成。细菌合成右旋糖酐用于生物被膜形成，致病菌则将其作为保护性包被以便入侵宿主的吞噬细胞。肠膜明串珠菌
右旋糖酐（Mw：25,000）可作为分析标准品，用于校准凝胶渗透色谱 (GPC) 的色谱柱。

Superparamagnetic iron oxide nanoparticles (SPIONs) are inorganic nanomaterials gaining strong clinical interest due to their increasing number of biological and medical applications. The stabilization of SPIONs in a biocompatible stable suspension (bioferrofluid) is generally achieved by an adequate polymeric coating.
