1. A system for microfluidic film evaporation, the system comprising:
a femtosecond laser-patterned substrate, comprising:
one or more femtosecond laser-patterned input paths for receiving at least one fluid; and
one or more femtosecond laser-patterned output paths,
wherein the femtosecond laser-patterned substrate causes the at least one fluid to wick from the one or more femtosecond laser-patterned input paths to the one or more femtosecond laser-patterned output paths, and
wherein the at least one fluid wicks in a thin film along a top surface of the femtosecond laser-patterned substrate; and
a heating device for heating the femtosecond laser-patterned substrate, thereby evaporating volatiles from the at least one fluid.
