The device uses microfabricated bioreactors to facilitate the on-demand production of therapeutic proteins for medicines and biopharmaceuticals. Making these miniature factories cell-free, which eliminates the maintenance of a living system, simplifies the process and lowers cost.
The bioreactor features elegance through a permeable nanoporous membrane and serpentine design fabricated using a combination of electron beam and photolithography and advanced material deposition processes. This design enables prolonged cell-free reactions for efficient production of proteins, making it easily adaptable for use in isolated locations and at disaster sites.
From a functional perspective, the design uses long serpentine channels integrated in a way to allow the exchange of materials between parallel reactor and feeder channels. With this approach, the team can control the exchange of metabolites, energy and species that inhibit production of the desired protein. Through other design features, researchers extend reaction times and improve yields.
The researchers also note that on-demand biologic synthesis would aid the production of drugs that are costly to mass-produce, including orphan drugs and personalized medicines.
