Encapsulated Ruthenium(II) Complexes in Biocompatible Poly(d,l-lactide-co-glycolide) Nanoparticles for Application in Photodynamic Therapy.

The elaboration, characterisation and efficiency of potential two-photon-excited photodynamic therapy (PDT) treatment of new poly(d,l-lactide-co-glycolide) nanoparticles loaded with ruthenium(II) complexs are presented. The materials are based on the encapsulation of Ru complexes through an all-biocompatible process. The size of the nanoparticles is around 100 nm.
