The disclosed radiosynthesis system utilizes droplet microfluidic technology to enable the parallel synthesis of radiolabeled compounds. This approach reduces reagent consumption and allows for high molar activity, even with low starting radioactivity. The system supports multiple reaction sites using either a single heater or multiple independently-controlled heaters. A specific embodiment features a four-heater setup on a multi-reaction microfluidic chip, which has demonstrated high repeatability in synthesizing various PET tracers.
The system is designed for droplet-based synthesis of radiolabeled compounds, enabling high throughput. It is particularly relevant for PET imaging, which requires rapid and efficient production of radioactive tracers. The technology addresses challenges in the field, such as the need for simultaneous radiolabeling of multiple compounds, while maintaining high specific activity for imaging purposes.
The system includes a microfluidic chip with discrete reaction sites, each capable of holding droplets for radiolabeling reactions. A heater platform with one or more heaters controls the temperature at these sites. The platform may include cooling devices to manage the temperature rapidly. Temperature sensors and control circuitry ensure precise thermal management, enhancing the system's efficiency.
The heater platform can accommodate multiple microfluidic chips, each with several reaction sites. For instance, a setup with four heaters and four chips can perform sixteen reactions simultaneously. Robotic fluid handling systems automate the loading and removal of fluids, although manual operations are also possible. This flexibility allows for various applications beyond radiochemistry, including organic synthesis and reaction optimization.
While primarily designed for synthesizing PET tracers, the system's applications extend to other chemical synthesis processes. It facilitates parallel synthesis and optimization, reducing the time and cost associated with developing new tracers. Additionally, it allows for screening experiments, comparing in vitro and in vivo properties, and optimizing reaction conditions with minimal reagent use.
