Abstract

A solvent-responsive polymer nanocapsule swells and deswells in response to a change in solvent composition, and the permeability of the shell of the nanocapsule can be controlled simply by swelling and deswelling; encapsulation and release of a fluorescent dye is achieved by a swelling-deswelling-swelling cycle.

摘要

一种溶剂响应性聚合物纳米胶囊会根据溶剂组成的变化而膨胀和收缩,并且仅通过膨胀和收缩就能控制纳米胶囊壳的渗透性;通过膨胀-收缩-膨胀循环实现荧光染料的包封和释放。
