▎ 摘　　要

NOVELTY - Device comprises photothermal film; a pyroelectric crystal over the photothermal film; and a superomniphobic surface over the pyroelectric crystal, where device is configured to move the liquid in the substantially loss-free operation with a beam of light. USE - Device for moving liquid in loss-free operation, used in measurement instrument and liquid transfer apparatus (all claimed). ADVANTAGE - The microfluidic platform enables locally addressable fluids to be navigated with a low loss rate and partitioned and merged in a readily controlled manner. The superomniphobic surface interfaces fluids in a frictionless manner via maintaining an ultrastable Cassie state and preventing liquid residues. The photothermal film is composed of graphene-polymer composite, which senses the light stimuli and responses by generating the localized and uneven thermogenesis. The pyroelectric crystal converts the heat into extra electric charges, forming a wavy dielectrophoretic force profile that can trap, dispense, and split fluids. The platform enables cargo carriers with droplet wheels and upgrading the limit of maximum concentration of deliverable protein by 4000-fold. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a measurement instrument comprising the device; (2) an apparatus for moving a liquid in a substantially loss-free operation; and (3) a method of transporting a liquid in a substantially loss-free manner, which involves irradiating a beam of light onto a superomniphobic surface, which is over a pyroelectric crystal, which is over a photothermal film, the liquid on the superomniphobic surface.
