Whiplash PCR (WPCR), which implements self-directed operation, programmed within a single DNA molecule, is a potential candidate for both mathematical and biological applications. However, WPCR-based methods are known to suffer from a serious efficiency problem called back-hybridization (BH). Previously, we proposed and partially validated a new rule-protect operation to abolish BH. In this work,...
In this paper, we propose an autonomous molecular walking machine using DNA. This molecular machine follows a track of DNA equipped with many single-strand DNA stators arranged in a certain pattern. The molecular machine achieves autonomous walk by using a restriction enzyme as source of power. With a proposed machine we can control its moving direction and we can easily extend walking patterns in...
