Corroles and corrole/transferrin nanoconjugates as candidates for sonodynamic therapy.

We report the utility of water-soluble corroles and also protein-coated nanoparticles (NPs) of lipophilic corroles as potent candidates for sonodynamic therapy (SDT), through the detection and quantification of the singlet oxygen that is produced by the ultrasonic irradiation of their aqueous solutions. Preliminary results on a cancer cell line provide evidence for the true utility of the NPs for SDT.
