Journal Article Journal of the Royal Society, Interface · August 2024 Natural biological branching processes can form tree-like structures at all scales and, moreover, can perform various functions to achieve specific goals; these include receiving stimuli, performing two-way communication along their branches, and dynamical ... Full text CiteLeak-resilient enzyme-free nucleic acid dynamical systems through shadow cancellation
Journal Article Journal of the Royal Society Interface · June 19, 2024 DNA strand displacement (DSD) emerged as a prominent reaction motif for engineering nucleic acid-based computational devices with programmable behaviours. However, strand displacement circuits are susceptible to background noise, known as leaks, which disr ... Full text CiteRecent Grants
