Title: Innovations of Jenn-Tzong Chen
Introduction
Jenn-Tzong Chen is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of nuclear energy and radiochemistry, holding a total of 13 patents. His work focuses on the purification and synthesis of radioisotopes, which are crucial for medical imaging and treatment.
Latest Patents
One of his latest patents is a method of high-pressure purification of [F-18]FEONM. This method provides a way to purify [F-18]FEONM under high pressure, integrating the synthesis processes of [F-18]FEONM. The process utilizes a non-toxic radio-high performance liquid chromatography (radio-HPLC) to purify the crude product. The method combines a conventional [F-18]FDG synthesizer with a novel radio-HPLC system in a heat chamber. After radiofluorinating the precursor, the reaction product is purified using an alumina solid-phase column to obtain the crude product while removing fluorine-18. A diphenyl semipreparative HPLC column is then used for final purification, employing a non-toxic solvent for mobile-phase elution to eliminate unreacted precursors and phase-transfer solvents. The radiofluorination achieves a reaction yield of about 50 percent, with an uncorrected radiochemical yield of 10^-20%. Both radio-HPLC and radio-thin layer chromatography (radio-TLC) demonstrate a radiochemical purity exceeding 95%. Another significant patent involves the fabrication of the [F-18]FEONM precursor, where 2-bromoethanol is added to connect an atom of oxygen at the N terminal of the precursor, enhancing fat solubility and improving brain imaging capabilities.
