AI Technical Summary
In existing technologies, traditional external mechanical oscillations or simple unidirectional rotating magnetic fields are difficult to drive magnetic beads to perform effective three-dimensional motion within a closed reaction vessel. Furthermore, existing magnetic field modes are limited and cannot adapt to samples of different viscosities and motion tasks. They also have low integration and are difficult to fit tightly to the curved surfaces of containers of different shapes.
A flexible programmable magnetic field is used to closely fit the reaction vessel through a flexible electromagnetic coil array, generating a variety of dynamic magnetic field modes, such as a horizontal eccentric rotation and a vertical pulse composite magnetic field. Combined with reinforcement learning algorithms, the magnetic field parameters are optimized in real time to achieve three-dimensional chaotic mixing and directional motion of the magnetic beads.
It achieves efficient mixing uniformity and precise control of directional movement of magnetic beads, adapts to different samples and tasks, simplifies system structure, is applicable to various reaction vessels, and improves automation and adaptability.
