Abstract

Abstract : Soft‐Contact Acoustic Microgripper In the article number 2104579, Jixiao Liu, Tiejun Li, and co‐workers utilize a controllable vibrating bubble gripper to realize noninvasive multi‐micromanipulations. The gas‐liquid interface oscillation excited by acoustic energy imposes coupled radiation force and drag force on the target micro‐bioentities for capturing and transportation. The flow velocity gradient generated by the streaming flow is utilized to rotate the immobilized micro‐object. It can be a powerful tool in 3D micromanipulation, 3D imaging of biological objects, and 3D cell mechanical properties analysis.
