Problems solved by technology

Furthermore, since many commercial automated systems are built for macroscopic synthesis, the process requires the consumption of large amounts of expensive reagents (such as precursors or Kryptofix 2.2.2), which is inefficient and ineffective for both clinical and research purposes. Economy

Embodiment Construction

[0071] In the following description, for purposes of explanation and not limitation, details and descriptions are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments that depart from these details and descriptions.

[0072] US Patent Application Serial No. 11 / 895,636, filed August 23, 2007, entitled "System for Purification and Analysis of Radiochemical Products Yielded by Microfluidic Synthesis Devices," is hereby incorporated by reference in its entirety.

[0073]In general, conventional automated synthesizers for synthesizing radiopharmaceuticals are inefficient, and highly efficient microfluidic reactors identified so far require manual operation. Various embodiments of the invention allow for automated operation of microfluidic reactors. Previous microfluidic reactors have been operated inside fixed leaded hot chambers thr...

Abstract

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.
