“…By using electrostatic interactions, it was also showed that a liquid droplet can be spontaneously coated with hydrophobic particles, resulting in multi‐layered LM . By exposing LM to an electric field provided by a capacitor, LM could be actively deformed and controlled their movements . Similar behavior was also reported for “Janus” marbles, which are droplets composed of two hemispheres characterized by presenting different physical and/or chemical properties.…”

Liquid marbles (LM) are freestanding droplets covered by micro/nanoparticles with hydrophobic/hydrophilic properties, which can be manipulated as a soft solid. The phenomenon that generates these soft structures is regarded as a different method to generate a superhydrophobic behavior in the liquid/solid interface without modifying the surface. Several applications for the LM have been reported in very different fields, however the developments for biomedical applications are very recent. At first, the LM properties are reviewed, namely shell structure, LM shape, evaporation, floatability and robustness. The different strategies for LM manipulation are also described, which make use of magnetic, electrostatic and gravitational forces, ultraviolet and infrared radiation, and approaches that induce LM self-propulsion. Then, very distinctive applications for LM in the biomedical field are presented, namely for diagnostic assays, cell culture, drug screening and cryopreservation of mammalian cells. Finally, a critical outlook about the unexplored potential of LM for biomedical applications is presented, suggesting possible advances on this emergent scientific area.

“…It was showed that LM can also be deformed, moved and can experience changes in their wettability when exposed to an electric field . Aussillous and Quéré showed for the first time that LM can be moved by the effect of an electrostatic field, where this field was reached by simply rubbing a stick of Teflon on a fabric .…”

“…The Bormashenko group has investigated the effect of an electric field on liquid marble shape and motion using an experimental apparatus to apply an electric field in a well‐defined manner . They demonstrated that a PVDF‐particle‐stabilized water marble placed on a glass slide could be stretched in the vertical direction in a uniform vertically applied electric field .…”

Liquid marbles" are liquid-in-gas dispersed systems stabilized by hydrophobic solid particles adsorbed at the gas-liquid interface. The structure, stability and movement of these liquid marbles can be controlled by external stimuli such as pH, temperature, light, magnetic and electric fi elds, ultrasonic, mechanical stress and organic solvents. Stimuli-responsive modes can be categorized into fi ve classes: (i) liquid marbles whose stability can be controlled by adsorption/desorption of solid particles to/from liquid surfaces, (ii) liquid marbles that can open and close their particle-coated surface by moving particles to and from the gas-liquid surface, (iii) liquid marbles that can move, (iv) liquid marbles that can change their shape and (v) liquid marbles that can be split. As a result of these stimuli-responsive characteristics, liquid marbles offer potential in the areas of controlled encapsulation, delivery and release.

“…This microliter droplet is made of water generally (because its high surface tension allows for the easiest LM formation), though glycerol is quite common [4], and even petroleum has been used [7]. This paper will focus on water-filled LMs.…”
