报告摘要:

Liquid marbles (LMs) aredroplets with volume of typically microliters coated with hydrophobic powder.The versatility, ease of use and low cost make LMs an attractive platform fordigital microfluidics. The talk will report our recent discoveries in thephysics of liquid marbles (LMs) that allow them to serve as miniature labs.First, a novel LM manipulation technique using dielectrophoresis (DEP) will bereported. Using this manipulation technique, the coalescence of two LMs wasdemonstrated via vertical collision. Next, the robustness of LMs wasinvestigated in terms of evaporation and structural deformation. Wedemonstrated that a LM cluster can survive thermal cycling conditions up to 95°C in a humidity controlledenvironment. The robustness of a LM in terms of elasticity was alsoinvestigated. Experimental results were compared with simulation based oncoarse grained molecular dynamics. The above proof-of-concept data show thatliquid marbles are suitable for applications such as large-scalethree-dimensional cell culture and high-throughput digital PCR.
