Korea Basic Science Institute 2 articles published in JoVE Environment Preparation of DMMTAV and DMDTAV Using DMAV for Environmental Applications: Synthesis, Purification, and Confirmation Hosub Lee1, Youn-Tae Kim2, Seulki Jeong1, Hye-On Yoon1 1Korea Basic Science Institute, Seoul Center, 2Natural Science Research Institute, Yonsei University This article presents modified experimental protocols for dimethylmonothioarsinic acid (DMMTAV) and dimethyldithioarsinic acid (DMDTAV) synthesis, inducing dimethylarsinic acid (DMAV) thiolation through mixing of DMAV, Na2S, and H2SO4. The modified protocol provides an experimental guideline, thereby overcoming limitations of the synthesis steps that could have caused experimental failures in quantitative analysis. Engineering Plasmonic Trapping and Release of Nanoparticles in a Monitoring Environment Jung-Dae Kim1, Yong-Gu Lee2 1Division of Scientific Instrumentation, Korea Basic Science Institute (KBSI), 2School of Mechanical Engineering, Gwangju Institute of Science and Technology (GIST) A microchip fabrication process that incorporates plasmonic tweezers is presented here. The microchip enables the imaging of a trapped particle to measure maximal trapping forces.
