    Toehold-mediated strand displacement with and without random pool strands. ( a ) Simplified depiction of a one-step TMSD process. The system consists of a single-stranded (ss) invader and a double-stranded (ds) reporter complex with a substrate strand which is labelled with a fluorophore and an incumbent labelled with a quencher. The short single-stranded overhang of the substrate, termed ‘toehold’ (depicted in red), is complementary to the toehold of the invader strand. Because of the sequence complementarity, the invader binds to the substrate and displaces the incumbent in a branch migration process. Eventually, the invader completely displaces the incumbent due to the higher thermodynamic stability of the invader–substrate complex. Separating the fluorophore from the quencher leads to an increase in <t>fluorescence</t> intensity, which can be used as a readout of the process. ( b ) TMSD process including a random pool strand that first forms a complex with the invader. The formation of a complex that occludes some of the toehold bases inhibits binding of the invader to the reporter, slowing down the overall displacement kinetics. ( c ) Schematic depiction of TMSD reactions in droplets. Invaders or invader–random pool complexes (green) are co-encapsulated with a reporter complex (orange) inside of a single droplet. After mixing of the droplet content, the TMSD reaction results in an increase in red fluorescence in the droplets. ( d ) Droplet production and monitoring of TMSD. TMSD reactants are encapsulated together in water-in-oil droplets in a microfluidic flow-focusing junction. Droplet sizes and mixing ratios can be controlled via the pressures applied to each inlet reservoir. In order to monitor TMSD reactions within droplets, the droplet flow is stopped instantly by applying a set of balanced pressures between inlets and outlets, directly followed by <t>microscopy</t> data acquisition downstream of the flow-focusing junction.

    Monitoring TMSD reactions in emulsion droplets. ( a ) Workflow for the extraction of kinetic parameters. Droplets are individually tracked from time-lapse fluorescence microscopy images. Reference (green) and reporter (red) fluorescence intensity values are obtained for each droplet for each time frame. The initial slope of the reporter intensity time course is chosen as a measure for the reaction kinetics. ( b ) Swarm plots of individual slopes after dividing each by the mean value of the set of experiments. The initial slopes show a much larger variability in the presence of a random pool. The red lines indicate Gaussian fits to the data. ( c , d ) Kinetic curves of individual TMSD reactions in a set of droplets generated in one experiment. Also shown is the mean of all droplet kinetic curves, and the kinetics for the same TMSD process recorded in a bulk experiment. Experiments were performed without ( c ) and with random pool ( d ), respectively.
