Title

Liquid marbles as a digital microfluidic lab-on-a-chip platform

Abstract
Liquid marbles (LMs) are droplets with volume of typically microliters coated with hydrophobic powder. The versatility, ease of use and low cost make LMs an attractive platform for lab on a chip. The talk will report our recent discoveries in the physics of liquid marbles (LMs) that allow them to serve as miniature labs. The talk will first report the generation and contactless manipulation of LMs using dielectrophoresis. The robustness of LMs was investigated in terms of evaporation and structural deformation. We then demonstrated that a LM can survive thermal cycling conditions up to 95°C in a humidity-controlled environment. Successful amplification of DNA with polymerase chain reaction (PCR) will be presented. Finally, three-dimensional cell culture and cryopreservation are presented to show that LMs can also serve as a versatile and scalable bioreactor platform.
