Phys.org  March 29, 2022 In general, DNA computation conducted in individual tubes is slow in generating chemical outputs in response to chemical inputs and requires fluorescence readout. Researchers at Emory University have introduced a new paradigm for DNA computation where the chemical input is processed and transduced into a mechanical output using dynamic DNA-based motors operating far from equilibrium. They applied DNA as a coating to extremely small glass beads. In practice, the glass beads either roll across the surface of a base of gold or hold steady, depending on how the DNA coating interacts with molecules that have been […]
