─光電融合で注目のQDレーザが持つ、シード光源メーカーというもうひとつの顔

Micro- and nano-scale particle manipulation techniques have enabled a diversity of clinical and engineering applications. Notable examples include the capture and sorting of cells and bioparticles at the single-cell level1, phenotypic profiling in diagnostics2, rapid and selective handling of heterogeneous targets in high-throughput microfluidics1,2,3, microfabrication and hierarchical assembly in materials engineering4, and mesoscopic quantum transport in condensed matter physics5,6. To achieve particle manipulation in a non-contact manner, a variety of field-mediated tweezers have been developed, including optical7,8,9,10, dielectrophoretic11,12, magnetic13,14, and acoustic tweezers15,16,17,18,19. These tools enable precise spatial control at the micro- and even nano-scales to support applications ranging from mechanophenotyping to quantum device assembly, without compromising the biological activity of cells or the physical coherence of quantum states. Among the various modalities of tweezers, optical tweezers (OTs) provide exceptional capabilities for nano-scale manipulation and piconewton-level force spectroscopy20,21,22. These capabilities facilitate applications such as the non-contact positioning and transport of single nanoparticles or cells with sub-micrometer precision23, as well as single-molecule assays for resolving force-extension behavior and kinetic transitions24. Furthermore, OTs can be tailor-shaped using structured light via holographic beams produced by wavefront shaping devices, such as spatial light modulators (SLMs), to generate Bessel, Airy, or Laguerre-Gaussian beam modes. This flexibility...
