Patent Number: 
Section: claims

1. A generator for a radioactive daughter nuclide comprisinga compound consisting of one of a group consisting of pyrogallol and catechol, and one of a group consisting of a saturated or unsaturated fatty acid having more than 3 carbon atoms, and a branched or straight-chain alkyl chain having more than 3 carbon atoms;a support selected from the group consisting of an organic support and an inorganic support comprising resin and silica gel, the compound being attached to the support via a nonpolar bond formed between the one of the group consisting of a saturated or unsaturated fatty acid having more than 3 carbon atoms, and a branched or straight-chain alkyl chain having more than 3 carbon atoms, and the support; anda parent nuclide, which is attached to the one of the group consisting of pyrogallol and catechol. 2. The generator according to claim 1, where the compound is dodecyl 3,4,5-trihydroxybenzoate. 3. The generator according to claim 1, wherein the branched or straight-chain alkyl chain having more than 3 carbon atoms is one of an octyl, decyl or octadecyl groups. 4. The generator according to claim 1 wherein said radioactive daughter nuclide is gallium-68 and said parent nuclide is germanium-68. 5. A generator for a radioactive daughter nuclide, comprising:a compound consisting of dodecyl 3,4,5-trihydroxybenzoate or 2 3-dihydroxynaphthalene;a support, the compound being attached to the support via a nonpolar bond; anda parent nuclide, which is attached to the compound via a functional group of the compound. 6. The generator according to claim 5, where the functional group of the compound comprises a hydroxyl group or a phenolic hydroxyl group. 7. The generator according to claim 5, where the functional group of the compound is pyrogallol or catechol. 8. The generator according to claim 5, where the support is selected from the group consisting of an organic support and an inorganic support comprising resin and silica gel. 9. The generator according to claim 8, where the silica gel is coated with the compound. 10. The generator according to claim 5, where the nonpolar bond is established by a molecular moiety of the compound. 11. The generator according to claim 10, where the molecular moiety is hydrophobic. 12. The generator according to claim 10, where the hydrophobic molecular moiety is selected from the group consisting of:an aromatic or heteroaromatic moiety;a saturated or unsaturated fatty acid having more than 3 carbon atoms; anda branched or straight-chain alkyl chain having more than 3 carbon atoms.
