Porphyrins based nanoreactors

Functionalization of nanoparticles with porphyrins and analogous macrocycles opened the way to important applications, such as, to name only a few gelators [8], phototherapy of cancer [9], degradation of organic pollutants by singlet oxygen photosensitization [10], and photoexcited electron transfer [11]. The interest in porphyrin-based nanoreactors lies in the possibility of using a variety of metals that can enter in catalytic processes [12].

A biocatalytic nanoreactor was also reported, made of acrylonitrile-based copolymers bearing porphyrin pendants that, after blending with CNTs, were electrospun into nanofibers. The nanofibers, in turn, were covalently bound to catalase, maintaining it in the active conformation [178]. As a consequence, the enzyme activity and stabihty improved.
