Our Optoelectronic Tweezers (OET) technology enables high-precision, non-contact manipulation of micro- and nano-scale objects through advanced optical field control. The system achieves sub-micron positioning and multi-degree-of-freedom control (translation, rotation, tilt) while supporting high-throughput parallel processing. It allows for simultaneous precision operations on multiple targets, significantly improving the efficiency and flexibility of complex micro- and nano-scale experiments.
