Abstract
We present a novel technique for capillary electrophoresis (CE) using terahertz (THz) waves, namely “THz-CE,” which enables us to sensitively detect separated substances in a solution flowing in a hollow of capillary whose inner diameter is smaller than 100 µm. Such THz detection could be achieved by utilizing the near-field interaction between a solution filled in a capillary and a point THz source that was locally generated by optical rectification in a nonlinear optical crystal irradiated with a femtosecond pulse laser. Here, we investigated the performance of THz-CE numerically and experimentally, and succeeded in observing the electrophoretic chromatogram for the separation between acetic acid and n-propionic acid by THz-CE.
期刊介绍：
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optical Materials Express (OMEx), OSA''s open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to:
Artificially engineered optical structures
Biomaterials
Optical detector materials
Optical storage media
Materials for integrated optics
Nonlinear optical materials
Laser materials
Metamaterials
Nanomaterials
Organics and polymers
Soft materials
IR materials
