Bionic behavior analysis of magnetic artificial cells

Abstract:

Cells are the mysterious source of life and the fundamental unit of all life activities in living organisms. The primary challenge in constructing a living artificial system lies in replicating the original form of life, namely, the cell. In order to create a system of cells with vitality, this paper innovatively proposed a design strategy. Specifically, by employing magnetic field programming to control clusters of magnetic particles encapsulated within droplets at gas/liquid interfaces, artificial cells with vitality were successfully fabricated. Furthermore, the paper conducted a detailed analysis of the underlying mechanisms driving their bionic behaviors, such as predation and parasitism. Firstly, by regulating the matrix droplets and magnetic field parameters of artificial cells, the basic life activities of cells in nature were reproduced, such as migration, predation, and parasitism. Then, according to the influence of the concentration, size, and liquid types of droplets on the behavior patterns of artificial cells, the paper revealed the underlying mechanism of the bionic behaviors of artificial cells. Finally, based on the predation and parasitism capabilities learned from the artificial cells, the paper designed and carried out a series of experiments on water surface pollutant removal and microchemical reactions. The results indicate that the artificial cell system presented here is of good stability and controllability, and it can achieve various bionic behaviors of cells. Moreover, it is expected to provide potential solutions for fields such as medical diagnosis and treatment, reagent testing, and environmental protection.
