Architectures for confined (inter)active chemistry

We consider supraparticles as a little chemical eco-system. The designable pores can be a “home for molecules”. This enables bridging molecular and nanoparticle chemistry all together in one system. Ultimately, we aim at enabling active, reactive and interactive chemistry in the confinement of a supraparticle and try to exploit this intriguing approach to design new energy, catalyst, sensor and indicator materials.
