Synthetic gene networks have wide-ranging uses in reprogramming and rewiring
organisms. To date, there has not been a way to harness the vast potential of
these networks beyond the constraints of a laboratory or in vivo environment.
Here, we present an in vitro paper-based platform that provides an alternate,
versatile venue for synthetic biologists to operate and a much-needed medium for
the safe deployment of engineered gene circuits beyond the lab. Commercially
available cell-free systems are freeze dried onto paper, enabling the
inexpensive, sterile, and abiotic distribution of synthetic-biology-based
technologies for the clinic, global health, industry, research, and education.
For field use, we create circuits with colorimetric outputs for detection by eye
and fabricate a low-cost, electronic optical interface. We demonstrate this
technology with small-molecule and RNA actuation of genetic switches, rapid
prototyping of complex gene circuits, and programmable in vitro diagnostics,
including glucose sensors and strain-specific Ebola virus sensors.
