Ship-in-bottle porphyrin-zeolite nanomaterials

In this paper, some metallo-porphyrins, like Co(II)-5,10,15,20-tetra-p-phenyl-porphyrin (CoTPP) and Co(II)-tetramethylphenylporphyrin (CoTMPP), were synthesized and encapsulated in different zeolites (X-71, MCM-41 etc.). In the encapsulated form, they exhibit photocatalytic properties and can also be used in the photodynamic therapy of cancer. The synthesized compounds were analyzed by means of some analytical methods, the most important being UV - spectroscopy and X-ray diffraction. Some preliminary photodynamic experiments of these new systems have been achieved (viability and proliferation) on cellular line (EL-4 and K562), by using He-Ne laser.
