    摘要: Methods and devices for a fully automated synthesis of radioactive compounds for imaging, such as by positron emission tomography (PET), in a fast, efficient and compact manner are disclosed. In particular, the various embodiments of the present invention provide an automated, stand-alone, hands-free operation of the entire radiosynthesis cycle on a microfluidic device with unrestricted gas flow through the reactor, starting with target water and yielding purified PET radiotracer within a period of time shorter than conventional chemistry systems. Accordingly, one aspect of the present invention is related to a microfluidic chip for radiosynthesis of a radiolabeled compound, comprising a reaction chamber, one or more flow channels connected to the reaction chamber, one or more vents connected to said reaction chamber, and one or more integrated valves to effect flow control in and out of said reaction chamber.

    摘要: A method for synthesizing an 18F-labeled probe. The method includes a step of eluting an amount of 18F with a first solvent which includes a predetermined amount of water and at least one organic solvent. In this step, the 18F elutes as an 18F solution. The method also includes a step of using the 18F solution to perform 18F-labeling in the presence of at least one labeling reagent and at least one phase transfer catalyst so as to generate the 18F-labeled probe. In the method, there is no step of drying the 18F starting from a time when the eluting step is performed and ending at a time when the 18F-labeling step is performed.

    摘要: A method for generating a radiolabeled tracer. The method includes providing a phosphine molecule having at least one carbocyclic, aromatic, or pyrrolidinyl ring with an OH substitute. The OH of this phosphines molecule is then condensed with an acid to produce a phosphine ester. Staudinger ligation is then performed to generate the radiolabeled tracer by treating the phosphine ester with a radiolabeled azide having a PET radioisotope moiety.
