From: Biomimetic Molecular Signaling using DNA Walkers on Microparticles
Demonstration of the catalytic circuit in solution. (a) Graph of fluorescence over time shows how the fluorescence of the DNA increases at different DNA walker concentrations. (b) End-point fluorescence micrographs of detector particles after incubation with DNA walker for one hour. (c) Average particle fluorescence as observed in the fluorescence microscope (error bars are the standard deviation of the averages of 3 images) (d) Schematic and end-point fluorescence micrographs showing the high persistence of the walker.
