Embodiment 1

[0033] figure 1 It is a schematic structural diagram of a liquid metal artificial cell according to an embodiment of the present invention; the liquid metal artificial cell includes: a semipermeable membrane 1, a liquid metal 2 and an electrolyte solution 4;

[0034] The semi-permeable membrane 1 is a closed cavity structure, and liquid metal 2 and electrolyte solution 4 are contained inside, thereby realizing the environmental response function similar to biological cells.

[0035] The semi-permeable membrane 2 is a polytetrafluoroethylene gas-permeable membrane that only allows water molecules to pass through but not solutes to pass through. The semi-permeable membrane 1 described in this embodiment is designed to be spherical with a diameter of 2 cm to simulate an oocyte-shaped closed cavity. In order to ensure that the liquid metal 2 is in a liquid state, the liquid metal 2 adopts a metal with a low melting point, that is to say, the melting point of the liquid metal 2 is...

Embodiment 2

[0042] figure 2 It is a structural schematic diagram of a liquid metal artificial cell according to an embodiment of the present invention. The shape of the artificial cell in this embodiment is a flat disc-shaped red blood cell, and the electrolyte solution 4 used is a sodium hydroxide solution with a concentration of 0.3 mol / L. All the other components and preparation method are consistent with Example 1. Here, the reason why the flat disc-shaped semi-permeable membrane structure is adopted is mainly to simulate red blood cells.

Embodiment 3

[0044] image 3 It is a structural schematic diagram of a liquid metal artificial cell according to an embodiment of the present invention. In this embodiment, except that the shape is long-axis, the rest of the components and manufacturing method are completely consistent with the embodiment 1. Here, the reason why the long-axis shape of the semi-permeable membrane structure is used is mainly to simulate the structure of neurons. Further, a dendritic structure may also be provided, which is not shown here.

Abstract

The invention provides a liquid metal artificial cell which comprises a semipermeable membrane, liquid metal and electrolyte, wherein a closed cavity is defined by the semipermeable membrane, the liquid metal and the electrolyte are located in the cavity. The invention further provides a preparation method for the liquid metal artificial cell. According to the liquid metal artificial cell, the technological concept of liquid metal artificial cell is introduced for the first time, a composite component system integrating the semipermeable membrane, the liquid metal, the electrolyte and more function materials into one is created, the existing knowledge of artificial cells and liquid metal is expanded significantly, the functions of the cells in the natural world can be simulated partly, and the liquid metal artificial cell can be further used for assembling an artificial machineswith more complex functions.

Description

technical field [0001] The invention belongs to the field of bionic technology, and in particular relates to a liquid metal artificial cell capable of partially simulating the environmental response function of biological cells and a manufacturing method thereof. Background technique [0002] Regardless of plants or animals, living organisms are the most complex substances for the entire earth and even the objects on the planet. After billions of years of evolution, the most fundamental thing that organisms surpass all other substances lies in their activity. We know that one of the most basic elements of living organisms is cells. Cells are the basic unit of structure and function of life. For example, the human body has about 40 trillion to 60 trillion cells with an average diameter of 10 to 20 microns, and there are many types, such as the largest mature egg cell, with a diameter of about 200 microns; the smallest is a platelet, with a diameter of only about 2 Microns,...
