胺封端的聚(酰胺基胺)树枝状聚合物的部分乙酰化已经用于制备与各种各样的功能配体(包括靶向部分、治疗剂和染料分子)缀合的树枝状聚合物颗粒。在部分乙酰化反应过程中的质量传输的有效性被发现有一个主要的影响,随后的树枝状大分子配体组分的分布,并成为批次之间的不一致的主要来源。这项研究具有广泛的纳米粒子-配体系统的广泛影响,因为它表明,具有相同的平均配体-粒子比的共轭物可以有完全不同的分布曲线。
Partial acetylation of the amine-terminated poly(amidoamine) dendrimer has been used in the preparation of dendrimer particles conjugated with a wide variety of functional ligands including targeting moieties, therapeutic agents, and dye molecules. The effectiveness of mass transport during the partial acetylation reaction was found to have a major effect on subsequent distributions of dendrimer–ligand components and to be a major source of inconsistency between batches. This study has broad implications for a wide range of nanoparticle–ligand systems because it demonstrates that conjugates with the same mean ligand–particle ratios can have completely different distribution profiles.
