Harnessing Ultrafast Optical Pulses for 3D Microfabrication by Selective Tweezing and Immobilization of Colloidal Particles in an Integrated System

3D Microfabrication Microfabrication using nano- to micron-sized blocks has transformative potential for next-gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. In article number 2500003, Kimani C. Toussaint Jr and co-workers introduce STIC, a single-laser system for precise colloidal manipulation and immobilization using femtosecond lasers, enabling efficient 3D assembly and imaging, advancing scalable, high-precision microstructure fabrication.
