On-chip transformation of Escherichia coli cells was accomplished for the first time using a microbial array chip. The continuous E. coli transformation procedures were performed on a chip in which the microcompartment was composed of PDMS microfluidic channels and a silicon substrate predeposited with different plasmid DNAs. The PDMS microfluidic device(More)
Rapid conversion of the line formation with the cells based on dielectrophoresis (DEP) was applied to simple and rapid distinction of cells with specific surface antigens from a cell population. The gap area of the interdigitated band array (IDA) electrode was modified with anti-CD33 antibody. Human promyelocytic leukemia cells (HL-60) which express CD33(More)
—In this work, we report the control of a microparticle position within fluid flow based on its size by using a repulsive force generated with negative dielectrophoresis (n-DEP). The n-DEP based fluidic channel, which was consisted of navigator and separator electrodes, was used to manipulate the particle flow in the center of channel and to control the(More)
