Microcapsules exhibit high encapsulation efficiency or molecular transport through the polymeric membrane depend on demands. The mixture of these microcapsules serves as a unit of a multiplex molecule detection or cascade enzyme reaction because of its independent, compartmentalized functions. Thus, the encoding process is essential to distinguish different microcapsules from a mixture. Here, we incorporated pre-formed graphical SU8 particles into the membrane that provide a direct identification of encapsulants, which does not affect the behavior of encapsulants and the polymeric membrane. The sub-microscale SU8 particles are dispersed in a photo-curable polymer mixture and generated in-situ encoding microcapsule by microfluidic system. Various types of encoding are possible due to the diverse morphology of SU8 particles. The ion-permeable microcapsules with different SU8 tags can applied to the multi-metal ion detection in water or wide range pH detection. |
