Characteristics of the Ringer’s solution-adjusted microemulsion-based isotonic perfusate (RS-ME), including droplet size distribution, as determined by NanoSight detection (a), the mean size and zeta potential of the RS-ME after storage for 0 and 1 month at 25 °C (b), transmission electron microscope imaging of the RS-ME (microemulsion) and its demulsification state after adding dimethyl sulfoxide (c), and the viscosity of the perfusate at 25 °C (RS, Ringer’s solution; RS-PEG, 20% [v/v] PEG 400 Ringer’s solution; RS-EtOH, 10% [v/v] ethanol Ringer’s solution) (d)
