Abstract
We have developed photo-induced pH-responsive systems using NBA that release protons via a photoinitiated reaction. The photo-induced pH jump reaction was integrated into various materials such as pH-responsive hydrogels, microfluidic devices, and nanoparticles. The spatio-temporal control of their properties upon photo irradiation has been successfully demonstrated. This technique can potentially be utilized to create smart platforms such as remote and programmed delivery of drugs or effective target molecule separation in the microfluidic channels.
