Abstract
Liquid metals (LMs) have received a lot of attention over the past decade. Gallium-based LMs are promising materials with high surface tensions, low viscosities and high electrical conductivity with applications in microelectromechanical systems (MEMS) and Liquid Metal Microfluidics (LMMF). However, several challenges should be tackled to generate reproducible and non-alloying plugs with a precise control over the size and spacing of the plugs in microchannels. They swiftly oxidize in air and form a nanometer-thick layer of gallium-oxide which lower the surface tension. In this talk, I present the history of LMMF and recent results about applications of LMs in Bio-MEMS.
