A functional nanoparticle with light-triggered charge reversal based on a protected amine-bridged polysilsesquioxane was designed. An emulsion- and amine-free sol-gel synthesis was developed to prepare uniform nanospheres. Photolysis of suspensions of these nanoparticles results in a reversal of the ζ potential. This behavior has been used to trigger nanoparticle self-assembly, nanocomposite hydrogel
设计了一种基于受保护的胺桥聚倍半硅氧烷的具有光触发电荷反转的功能性纳米颗粒。开发了一种不含乳液和胺的溶胶-凝胶合成方法来制备均匀的纳米球。这些纳米颗粒悬浮液的光解导致 ζ 电位的逆转。这种行为已被用于触发纳米粒子自组装、纳米复合水凝胶形成和纳米粒子释放,显示了这种材料在纳米级操作和纳米粒子治疗中的潜力。
