For this study, we considered MNLDs with a stable and strong dispersion of Fe3O4 NPs [equivalent to the case discussed in Fig. ], as stated in the Materials and Methods section. Our parametric analysis only considers the effect of varying drop volumes and MNP concentrations inside the drops on the aggregation and de-encapsulation, with all the other variables affecting the process being kept constant in the experiments. Based on trial runs, the drop release distance (hdr) was kept constant at 20mm from the base of the container, the concentration of MNPs (CMNP) was varied between 10 mg/ml to 20 mg/ml, and the drop volumes (Vd) were set at 10, 15, and 20 microliters: these combinations of the CMNP and Vd ensured that the MNLD moved downwards towards the magnetic stack and the dispersions inside the drop can be treated as strong dispersions. For this domain of experimental parameters, it was observed that all the MNPs in an MNLD didn't completely aggregate within the time frame of the MNLD reaching the datum line. In addition, the amount of MNPs that aggregated inside the drop prior to de-encapsulation defined the amount of magnetic force acting on the aggregates that drove them to de-encapsulate; this stemmed from the fact that Fmag ∝ VMNP, where VMNP is the volume of MNPs that form an aggregate inside the MNLD.
