The purpose of this study is to find the differences of speeds between disease-causing cells and healthy cells under alternating current electric field in 3D multi-layered microchannel. We prepared intracellular charge-differed two cell types: wild type cells (WT) and wild type cells with green fluorescent protein (GFP)-histone (GFP-HT). The cell dynamic movement of each type was detected by cell tracking. We found a difference between WT velocity and GFP-HT velocity around supplying electrode and discussed by particle tracking velocimetry. The present results provide a great significance for separation of disease-causing cells from healthy cells in the microchannel.","PeriodicalId":165544,"journal":{"name":"2015 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"62 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":"116145220","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}

In this paper, we describe a new scheme for continuous particle sorting, using high-density, lattice-shaped, and dual-depth microchannel networks. The lattice pattern composed of perpendicularly crossing deeper “main channels” and shallower “separation channels”, and the main channels are slanted against the overall flow direction. When particle suspension is continuously introduced, smaller particles reach the ceiling of the main channel, whereas larger particles do not. Consequently, larger particles enter the separation channels more frequently, resulting in the continuous particle separation. In the experiment, we successfully sorted microparticles based on size. In addition, the effects of the microchannel geometries and the vertical position of particles on the sorting efficiency were investigated. As application to biological samples, we demonstrated cell sorting using cultured mammalian cells. The presented mechanism of size-based particle sorting would be applicable to various research and industrial fields.","PeriodicalId":165544,"journal":{"name":"2015 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"96 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":"125984701","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}

A general micro fluid system, a flow channel and the pump part, other, it's separated. So miniaturization is difficult. As the countermeasure, the flow pass part and the pump part, technology of the hollow tube micro pump with which I united is applied. Ring type PZT is arranged to the needle top by applying the technology. Therefore a needle makes itself work as a pump. By the flow experiment, liquid transport in the tube of the hollow tube micro pump has been confirmed. Though, the flow rate through the tube is very small.Therefore, due to the radial direction of the deformation increase in the amount of ring type PZT, it is necessary to pump performance improvement. Check on the analysis that the amount of deformation increase is by adding a trench on the surface of the ring type PZT. However Optimization contributing trench condition deformation amount is not performed. Therefore, in order in this study to further improvement of the pump performance. The use of FEM analysis for ring type PZT, which went to a put a trench. Is one of the trench conditions, attention is focused on the trench rate. First, the static structural analysis is carried out to search for the best trench proportions. Then the modal analysis, the best trench ratio model and confirms the natural frequency. And performs frequency response analysis, and confirms the amount of deformation caused by each frequency. To target model which is arranged a PZT on the titanium tube.

Protein molecules were precipitated, and then stable protein microparticles were obtained after the crosslinking reaction. We obtained spherical/non-spherical protein microparticles using several types of proteins, and examined factors affecting the particle morphology. In particular, highly unique tear-drop-shaped particles and hemispherical particles were obtained when incompletely dehydrated droplets were crosslinked.
