Researchers have developed an innovative method for manipulating microparticles using optoelectronic tweezers (OETs). This technique allows for the controlled assembly, disassembly, and self-propulsion of microparticle ensembles through a light-induced electric field. This advance is significant because it offers unprecedented precision and flexibility in micro-manipulation, overcoming the limitations of traditional methods that often require physical contact or are less versatile for complex structures.
