Abstract: A method is provided to purify [F-18]FEONM under a high pressure. The synthesis processes of [F-18]FEONM are integrated. An isolation process of non-toxic radio-high performance liquid chromatography (radio-HPLC) is used to purify the crude product. The method integrates a convention [F-18]FDG synthesizer and a novel radio-HPLC system together in a heat chamber. After radiofluorinating the precursor, the reaction product is purified with an alumina solid-phase column in advance to obtain the crude product while fluorine-18 is removed. Then, diphenyl semipreparative HPLC column is used for a final purification. A non-toxic solvent is used for mobile-phase eluting to remove the unreacted precursor and the phase-transfer solvent. The radiofluorination has a reaction yield about 50 percent (%). The method has an uncorrected radiochemical yield of 10˜20%. Both of the radio-HPLC and the radio-thin layer chromatography (radio-TLC) have radiochemical purity higher than 95%.

Abstract: The present invention relates to a preparation method of a carrier containing a radiolabeled colloid, which comprises the following steps: adsorption: putting a carrier into a radioisotope water solution, and reacting for 5-20 minutes to obtain a first solution; coating: adding a solvent capable of enabling a colloid to be formed into the first solution, and reacting for 5-20 minutes to obtain a second solution; and purification: centrifuging the second solution to form a first supernatant and a first precipitate, removing the first supernatant, cleaning the first precipitate with deionized water, centrifuging to form a second supernatant and a second precipitate, and finally, removing the second supernatant, wherein the residual second precipitate is the carrier containing the radiolabeled colloid.

Abstract: A surface-modified microsphere composition comprises poly(lactic-co-glycolic acid) (PLGA), chitosan, hydrophobic drug, and hydrophilic drug. The PLGA forms a microsphere. The chitosan is formed on a surface of the microsphere. The hydrophobic drug is encapsulated by the microsphere. The hydrophilic drug is adsorbed on the surface of the microsphere. The surface-modified microsphere composition is for treating arthritis. A method of preparing a surface-modified microsphere composition involves producing by an oil-in-water emulsion method microspheres formed from PLGA, covered with chitosan, and adapted to encapsulate hydrophobic drug, and having hydrophilic drug adsorbed on their surfaces. The surface-modified microsphere composition enables drug to be released to achieve efficacy both instantly and persistently.

Abstract: Albumin and doxorubicin are bonded through reaction. The bonded albumin and doxorubicin are added with a gold-nanoparticles solution for reaction. After being purified with water in a column, the liquid phase of gold-nanoparticles is changed into a phosphate buffer for obtaining an anticancer drug having doxorubicin bonded with gold nanoparticles. Thus, with the high biocompatibility and the big surface areas, gold nanoparticles are used in biological applications and used as carriers for increasing drug accumulation on tumor. The bonding between gold nanoparticles and doxorubicin increases stability of doxorubicin. Besides, doxorubicin has tumor-killing effect for cancer therapy.
