Liquid metal can imitate the behavior of white blood cells, which includes change and obstacle navigation

Scientists led by Prof. Liu Jing of the Technical Institute of Physics and Chemistry of the Academy of Sciences of China (CAS) have created a liquid metal entity similar to leukocytes that vividly simulate several leukocyte behaviors in nature.

In an article published In the newspaper Affair On February 10, researchers demonstrated how these “liquid metal leukocytes” can perform complex actions autonomously, such as wrapping strange substances, changing shape, moving pulsatile and even rising against gravity, showing surprising similarities with dynamic behavior of living cells.

The research team, collaborating with the University of Tsinghua, introduced a novel approach by combining chemotaxis and asymmetric chemical mechanisms. This synergy allows liquid metal to exhibit diverse and autonomous behaviors similar to those of real leukocytes, such as complex surfaces for forming and navigation.

According to researchers, these liquid metal structures can scale slopes up to 5 ° on their own and move through complicated surfaces, highlighting their versatility and potential for future applications. In addition, they can easily change their shape and adapt well to avoid obstacles, making them very versatile and capable.

The central principle is that the self -adaptive surface tension of liquid metal changes continuously during its alternate oxidation, reduction and dexidation processes. The experiments also confirmed that the liquid metal leukocyte is based on the conversion of substances and the differences of electrochemical energy in their environment, which allows it to move dynamically.

This chimiotoxic liquid metal system shows great potential for various applications, including adaptable, microfluid and medical therapies. In addition, it opens new paths to develop advanced nature simulation systems that imitate several living organisms, marking the beginning of a new border at the intersection of material science and synthetic biology.
