Summary

Gels can be used as responsive systems for many applications. By using microgels, particles with various functionalities and sensitivities including drastic size change under certain conditions or multiple-functionalities (Janus particles) can be fabricated. By using a microfluidic device along with precursor polymers which consist of multiple polymeric units and contain the desired functionalities, different types of microgels can be fabricated.
