The "endocytosis effect" of cells phagocytic to external particles is a common behavior in the biological world, but have you thought that metals can also swallow the surrounding particles like biological cells? Through research, Chinese scientists have discovered this magical biological behavior of liquid metal. A few days ago, this research was published in the cover of the international authoritative journal "Advanced Science".
Unlike solid metals in the conventional environment, gallium-indium alloys remain liquid even at room temperature, which is what we often call liquid metals. A joint research group between the Institute of Physics and Chemistry of the Chinese Academy of Sciences and Tsinghua University found that liquid metal droplets in a solution environment, when subjected to electric fields or chemicals, produce an endocytic effect similar to that of cells phagocytizing external particles, enabling efficient surrounding The particles are swallowed into the body. This discovery has also opened up a new way to build high-performance nano metal fluid materials.
This magical phagocytosis is not the only biological behavior of liquid metal. The team also found that when the metal droplets were partially immersed in an alkaline solution and partially exposed to air, the solution at the interface between the liquid metal and the air would oscillate regularly.
Liu Jing, a professor at the Institute of Physics and Chemistry of the Chinese Academy of Sciences, Tsinghua University: From the experimental observation, it is like an alveoli. So we named it breathing. It is completely dependent on the interaction of this environment, air or solution, it is a bit like life.
According to reports, liquid metal has many characteristics such as autonomous morphological changes, and can exhibit many magical changes under the action of electric field magnetic field. It can be widely used in 3D printing, flexible intelligent machines, vascular robots, etc., new discoveries of biological behaviors. It will further explore new areas of liquid metal research.
