11. In porphyrin systems, the zinc ion appears to hinder the photodynamic activity of the compound. 12. Photodynamic therapy is gaining in popularity.13. Other innovations include harnessing sunlight for space communications and meteorological information; controlling photodynamic cancer therapy. 14. It has also been tested for use in photoangioplasty ( photodynamic treatment of diseased arteries ). 15. Because of their photosensitivity, chlorins are in active use as photosensitizing agents in experimental photodynamic therapy. 16. The manganese pyridiniumyl derivative has shown the highest photodynamic activity, while the nickel analogue is photoinactive. 17. The hydrophilic sulphonated porphyrins and PCs ( AlPorphyrin and AlPC ) compounds were tested for photodynamic activity. 18. Photodynamic therapy ( PDT ) with verteporfin has shown promise as an effective treatment with minimal complications.19. Photodynamic therapy ( PDT ) with several photosensitizers is a promising modality for the treatment of cancer.20. Photodynamic therapy is a new angle on cancer treatment, and seeks to use light in fighting tumors.
