Optical fibre gripper for high-performance 3D micromanipulation

Researchers developed a miniature three-dimensional optical fibre gripper on June 17, 2026, enabling high-performance micromanipulation of particles and single cells within confined spaces. This innovation effectively bridges the capabilities of optical tweezers and mechanical grippers, offering enhanced precision and force for delicate manipulation tasks. The gripper utilizes a focused laser beam to trap and move microscopic objects, providing a non-contact method that minimizes damage to sensitive biological samples. Its three-dimensional control allows for complex manipulation trajectories, which is crucial for applications in fields like cell biology, micro-assembly, and advanced materials science. The published research in Nature highlights the gripper's ability to exert significant forces, surpassing typical optical tweezers, while maintaining sub-micron accuracy. This advancement is expected to accelerate research in areas requiring precise handling of individual cells or nanoparticles, such as in vitro fertilization, drug delivery system development, and the creation of micro-scale devices. The technology's compact design also makes it suitable for integration into existing microscopy setups and microfluidic devices, broadening its potential applications across various scientific disciplines. The development represents a significant step forward in the field of micro-robotics and precision manipulation.
