Researchers have demonstrated a technology capable of a suite of data storage and computing functions -- repeatedly storing, retrieving, computing, erasing or rewriting data -- that uses DNA rather than conventional electronics. Previous DNA data storage and computing technologies could complete some but not all of these tasks.
Researchers from North Carolina State University and Johns Hopkins University have demonstrated a technology capable of a suite of data storage and computing functions -- repeatedly storing, retrieving, computing, erasing or rewriting data -- that uses DNA rather than conventional electronics. Previous DNA data storage and computing technologies could complete some but not all of these tasks.
"Specifically, we have created polymer structures that we call dendricolloids -- they start at the microscale, but branch off from each other in a hierarchical way to create a network of nanoscale fibers," says Orlin Velev, co-corresponding author and the S. Frank and Doris Culberson Distinguished Professor of Chemical and Biomolecular Engineering at NC State.
"You could say that Keung's team is providing the equivalent of microcircuits, and the dendricolloidal material that my team creates provides the circuit board," says Velev."Our NC State collaborator Adriana San Miguel helped us incorporate the materials into microfluidic channels that direct the flow of nucleic acids and reagents, allowing us to move data and initiate computing commands.
"There's a lot of excitement about molecular data storage and computation, but there have been significant questions about how practical the field may be," says Keung."We looked back at the history of computing and how the creation of ENIAC inspired the field. We wanted to develop something that would inspire the field of molecular computing. And we hope what we've done here is a step in that direction.".
