Abstract: An optical element driving mechanism includes a movable assembly, a fixed assembly, and a driving assembly. The movable assembly is configured to be connected to an optical element. The movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly in a range of motion. The optical element driving mechanism further includes a positioning assembly configured to position the movable assembly at a predetermined position relative to the fixed assembly when the driving assembly is not operating.

Abstract: The present disclosure provides a decellularized extracellular matrix, the preparation process and uses thereof. The decellularized extracellular matrix of the present disclosure is derived from a three-dimensional cell spheroid, and the decellularized extracellular matrix has a three-dimensional spherical structure. The decellularized extracellular matrix of the present disclosure can be used to prepare a biomedical material scaffold for promoting tissue regeneration and repair.
