Abstract
Liquid marble, an emerging platform for digital microfluidics, has shown its potential in biomedical applications, cosmetics, and chemical industries. Recently, the manipulation and fundamental aspects of liquid marbles have been reported and attracted attention from the microfluidics community. Insights into their physical and chemical properties allow liquid marbles to be utilised in practical applications. This review summarises and revisits the effect of capillarity on the formation of liquid marbles and how it affects the effective surface tension as well as their robustness. The paper also systematically discusses the applied aspect of capillarity of the carrier liquid for transporting floating liquid marbles.
