Abstract
It is shown that the activity of the water-soluble porphyrin photosensitizer dimegine (DMG) in the oxidation reaction of tryptophan, a test reaction for photodynamic therapy (PDT), can be enhanced by introducing silver, gold, and hydroxyapatite nanoparticles (NP) into the reaction medium if an amphiphilic polymer (AP) with the properties of a SAS is introduced into this mixture. It is concluded that the effect of enhancing the photosensitizing activity of dimegine is due to the formation of nanoparticle-Pluronic-porphyrin triple systems in which Pluronic (PL) plays the role of a bridge, forming complex and adsorption bonds with porphyrin and nanoparticles.
