The recovery of these materials from water is required to reduce the risk of cytotoxicity. To investigate surface interactions related to the separation of micro/nanoparticles in water, we attempted to float TiO2, SiC, multi-walled carbon nanotubes (MWCNTs), and carbon fiber (CF) using MBs generated by electrolysis. After MBs were generated for 5-10 min by applying a voltage between two electrodes, SiC, MWCNT, and CF were aggregated on the surface of the tap water in the container. However, hydrophilic TiO2 remained well dispersed in water and did not aggregate after the generation of MBs. These results demonstrated that hydrophobic micro/nanoparticles in water can be separated by floatation and aggregation on the surface of water using this MB-generating method. We also measured the ζ-potential of MB-containing water; the recorded potentials ranged from -12 mV to -19 mV. The pH of this MB-containing water was 5.6. Based on the measured ζ-potential, the electrostatic interaction between MBs and the floating particles would not contribute to adsorption of MB and these particles. Therefore, the hydrophobic interaction with MBs can be used for the purification and separation of hydrophobic micro/nanoparticles.","PeriodicalId":165544,"journal":{"name":"2015 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115328880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Holographic optical elements, which are attracting attention in the field of optical elements, can satisfy these demands. For this study, a prototype precision positioning device of a dual servo mechanism was designed and produced for microtrench processing. The coarse motion actuator incorporates a ball screw and a linear guide. Also, a laminated type piezoelectric actuator is used as a micro-motion actuator. A laser length measuring device was used to evaluate the precision positioning of the device. This study also examined a method for compensation of hysteresis by polynomial function fitted to displacement-voltage data and displacement characteristics of the piezoelectric element. Furthermore, for decreasing voltage, compensation by the lowest ordered second-order polynomial function must be preferred because no great difference in compensation performance was recognized in compensation by three different polynomials.","PeriodicalId":165544,"journal":{"name":"2015 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121696978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, usage of oil causes cellular damage. In this study, we aimed to establish a new method for forming cell-embedded ECM capsules without using oil. We also report “ECM-loaded spheroids” which is a different type of cell-embedded ECM capsules having less amount of ECM. To form ECM capsule, we utilized the methylcellulose (MC) medium [1]. We injected 1 μl of undiluted ECM (Matrigel or collagen) suspending 2000 Hep G2 cells into the MC medium. The cellular damage was obviously reduced when we made capsules by the MC medium. However, the albumin secretion activity of the Hep G2 cells in ECM capsule was half level compared with normal multicellular spheroids because too much gels inhibited cell-to-cell interaction. When we used 30-times diluted Matrigel, the thickness of gel between cells was significantly reduced. In this study, we called this kind of spheroid with ECM as “ECM-loaded spheroid”. The albumin secretion activity of ECM-loaded spheroids was higher than that of normal spheroids. In conclusion, we established a new method to fabricate ECM capsules and ECM-loaded spheroids, and ECM-loaded spheroids demonstrated higher hepatic function than conventional spheroids.","PeriodicalId":165544,"journal":{"name":"2015 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"308 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114048856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
