OptoBot®500 Optoelectronic Tweezer System

In the microscopic world, enabling complex 3D motions in micron-scale machines has long been a scientific challenge. Traditional micromachines are confined to 2D planar motion, limiting their ability to perform multitasking operations in complex microenvironments.

In modern science, a technology that harnesses the combined power of light and electricity to manipulate microscopic objects—​​Optoelectronic Tweezers (OET)​​—stands as a marvel.

Optoseeker collaborated on groundbreaking optoelectronic tweezers (OET) research, "Automated and collision-free navigation of multiple micro-objects in obstacle-dense microenvironments using optoelectronic tweezers," published in Microsystems & Nanoengineering.

Optoseeker Empowers Scientific Breakthrough! Optoelectronic Tweezers Graces Top Journal, Ushering in the "Three-Dimensional Era" of Micro-Manipulation Warm congratulations to the collaborative research team from Beijing Institute of Technology, University of Toronto, and other top institutions for their groundbreaking paper published in Advanced Materials! By utilizing programmable light patterns within an optoelectronic tweezer (OET) system, the team achieved 3D motion and cross-plane motion transfer in multi-component micromachines. Their work, entitled "Crossing the Dimensional Divide with Optoelectronic Tweezers: Multicomponent Light-Driven Micromachines with Motion Transfer in Three Dimensions," appears in the prestigious Advanced Materials (Impact Factor: 27.4). Notably, ​​Optoseeker​​ played a deep role in this achievement, providing robust technical support for system development and commercialization through its exceptional engineering capabilities.

Optical micromanipulation—including techniques that use light to trap and manipulate microscopic objects—was revolutionized by Arthur Ashkin’s invention of the optical tweezer in the 1980s. Optical tweezers rely on gradient and scattering forces from a tightly focused laser beam to control micro‑objects; while highly effective in controlled settings, they face limitations when handling targets of varying size, shape, or refractive index, and their high‑intensity beams can damage sensitive biological samples (e.g., cells).
