Janus Liquid marbles (JLMs) are next-generation liquid marbles enwrapped with multi-particles of different sizes, hydrophobicity, and/or chemical properties. The functionally distinct surface of Janus Liquid marble enables the selective and precise manipulation of liquidmarble in a controllable manner. Here, we present an efficient method to tune the particle coverage of Janus Liquid marble by controlling the surface tension of the core liquid. The impact-based fabrication strategy is used for the continuous productionof JLMs of different volumes. The tunability in particle coverage is achieved for JLMs of volumein the range 5-10 μL. A simple energy balance analysis is employed for the theoretical estimation of the maximum spread parameter (β m ) and found to be in reasonableagreement with the experimentally measured value.
