Figures and show the distributions of LAB and L † AB, respectively, in an A:B-droplet at several normalized simulation time steps (the white broken-line circle indicates the surface of the A:B-droplet). In the present study, we fixed the percentages of LAB and L † AB to the total amount of linker DNA to 90% and 10%, respectively. We referred to previously reported kinetic parameters and diffusion coefficients . The results show that L † AB remains longer than LAB, although the percentage of L † AB is lower than that of LAB. This indicates that the decrease of L † AB becomes slower due to the time-delay circuit.
