Chemical reaction networks make up an old language of equations that detail how chemicals behave together. Now engineers at the University of Washington are taking this language into the 21st century with a computer program for chemistry that can help direct the movement of synthetic molecules.
This standardized set of instructions on how to “program” how DNA molecules interact in a test tube or cell could pave the way for smart drug delivery systems and disease detectors at the cellular level, the researchers report this week in the journal Nature Nanotechnology.
“We start from an abstract, mathematical description of a chemical system, and then use DNA to build the molecules that realize the desired dynamics,” author Georg Seelig, a UW assistant professor of electrical engineering and of computer science and engineering, said in a school news release. “The vision is that eventually you can use this technology to build general-purpose tools.”
Seelig calls his team’s approach a “programming language” because, he says, much like how programming langua… [Read more]
