摘要： A preparation method of a miniature intelligent calcium alginate hydrogel end operator based on different microelectrodes is introduced. The method includes an electrodeposition step of depositing a deposition solution under the action of a non-uniform magnetic field to form an anode surface; a processing step of transferring obtained hydrogel microstructures to a calcium chloride solution, making the hydrogel microstructure self-wind sufficiently; and a pickup step of collecting a self-winding single-layer film alginate microstructure in a culture dish, and placing it in specific environment for preservation. The preparation method can provide a degradable and convenient micro-operator, which could be locally prepared into different function components.
