Micro container made of levitated liquid bead

Year: 2024

Type: article

Abstract: Liquid bead, an emerging digital microfluidic platform offers wide range of application in research and industry. Making liquid bead using acoustic levitation technology allows for the fabrication of micro container. Extensive insight into levitated liquid beads is essential for determining their performance. Firstly, this paper unfolds the unique interface of the levitated liquid bead, which has thin membrane of shell material on top and thus serves as a micro container. Next, we characterised the puncture toughness of liquid beads to assess the capability of releasing the liquid content. Liquid bead with larger corresponding shell volume and lower core volume recorded highest resistance against penetration. Finally, we observed the thermal behaviour of liquid beads at elevated temperature. The liquid beads showed no morphological change over 10-minutes period at 50 °C. Liquid bead exceeded critical temperature threshold at 65 °C, which resulted in breaking the thin membrane and releasing of liquid from the core.
