Abstract: The present invention relates to a method using nanoparticles of cyclic tetrapyrrolic compounds as gene and drug delivery agents. Pharmaceutical agents can be packed or condensed inside nanoparticles of cyclic tetrapyrrolic compounds and delivered to cells. In vitro experiments showed nanoparticles of cyclic tetrapyrrolic compounds can be effectively delivered into cells.

Abstract: The present invention relates to a method to prepare porphyrin nanoparticles and its application as oxidation catalyst. Mixing solvent techniques was used to prepare porphyrin nanoparticles. The sizes of the resulted porphyin nanoparticles are in the range of 1-1000 nm. The resulted porphyrin nanoparticles were characterized by DLS, AFM and UV-Vis. The nanoparticles are stable in air from weeks to months and has been successfully transferred to Al2O3 and silica gel surface. The present invention also related to a method to use nanoparticles of porphyrins as catalyst for epoxidation reactions of olefins and hydroxylation reactions of saturated hydrocarbons. By loading the nanoparticles onto the surface of Al2O3 and silica gel, excellent catalytic activities were obtained in oxidation reactions.
