Query: Inverse Leidenfrost drop manipulation using menisci   Drops deposited on an evaporating liquid bath can be maintained in an inverse
Leidenfrost state by the vapor emanating from the bath, making them levitate
and hover almost without friction. These perfectly non-wetting droplets create
a depression in the liquid interface that sustains their weight, which
generates repellent forces when they approach a meniscus rising against a wall.
Here, we study this reflection in detail, and show that frictionless
Leidenfrost drops are a simple and efficient tool to probe the shape of an
unknown interface. We then use the menisci to control the motion of the
otherwise elusive drops. We create waveguides to direct and accelerate them and
use parabolic walls to reflect and focus them. This could be particularly
beneficial in the scale up of droplet cryopreservation processes: capillary
interactions can be used to transport, gather and collect vitrified biological
samples in absence of contact and contamination.
