Area of Science:

  • Radiochemistry and Nuclear Medicine
  • Microfluidics and Lab-on-Chip Technology
  • Chemical Engineering and Process Design

Background:

  • Microfluidics offers advantages for Positron Emission Tomography (PET) tracer synthesis, particularly in temperature control.
  • Developing a compact, commercializable microfluidic platform for complete PET tracer synthesis workflows remains a significant challenge.

Purpose of the Study:

  • To design and validate an integrated microfluidic platform for automated PET tracer synthesis, addressing commercialization hurdles.
  • To develop a cost-effective, mass-manufacturable lab-on-chip solution for radiochemistry.

Main Methods:

  • An integral system design approach was used, focusing on material compatibility and mass manufacturing.
  • The platform integrates on-chip valves, solid-phase extraction (SPE), reactors, and a reversible fluid interface.
  • An automated chip-machine interface, vial-based reagent supply, and efficient reagent transfer were incorporated.

Main Results:

  • All functional elements of the microfluidic platform were successfully validated.
  • The platform was demonstrated for the automated synthesis of a Gastrin-releasing peptide receptor (GRP-R) binding PET tracer, ([(18)F]PESIN).

Conclusions:

  • The developed microfluidic platform offers a compact and integrated solution for PET tracer synthesis.
  • This approach facilitates cost-effective lab-on-chip mass manufacturing and addresses key commercialization challenges in radiochemistry.
