Dynamic covalent bonds are established upon molecular recognition of sugar derivatives by boronic acid molecules. These reversible links can be used in a cross‐linking method to fabricate polymer‐based responsive nanosystems. Herein, the design of the first dynamic nanogels made entirely of polysaccharides (PS) is reported. Based on PS chains alternately modified with phenyl boronic acid groups and sugar moieties, these colloids self‐assemble in physiological conditions and combine the biocompatible nature of their PS backbone with the reconfiguration capacities of their cross‐linking chemistry. These dynamic nanogels are easily prepared, stable for a long time, pH responsive, and efficiently internalized by cancer cells.

动态共价化学实现了可重构的全多糖纳米凝胶。

当硼酸分子对糖衍生物进行分子识别时,建立动态共价键。这些可逆连接可用于交联方法中,以制造基于聚合物的响应纳米系统。在此,报道了完全由多糖(PS)制成的第一动态纳米凝胶的设计。这些胶体基于被苯基硼酸基团和糖基团交替修饰的PS链,可在生理条件下自组装,并将其PS骨架的生物相容性与交联化学的重构能力结合在一起。这些动态纳米凝胶易于制备,可长期稳定,对pH敏感,并可以被癌细胞有效地内化。
