| 报告介绍 | 报告摘要：
This talk will highlight our recent study of nanoparticle (NP) crossing oil/water interfaces. By anchoring stimuli-responsive polymer brushes on their surfaces, NPs can readily transfer between water and oil across oil/water interfaces in response to the environmental change in ionic strength, pH, and temperature for instance. This NP crossing interfaces is obviously associated with the hydration and de-hydration of the NP polymer brush coating, which is determined dominantly by the hydrogen bonding of the polymer brushes with water. The new interface causing properties of NPs will also lead to new design of vehicles to deliver biological labels and therapeutic substances to cross biological barriers. |
