The goal of this article is to make a pattern of human induced pluripotent stem cells (hiPSCs) on a Polydimethylsiloxane (PDMS) surface. Here, we report that pattering of hiPSCs can be achieved by patterned plasma treatment followed by coating with a two protein mixture. The result is useful for future applications of micro devices in human cell culture.
We proposed and demonstrated autonomous tweezers driven by surface tension without any actuators. The tweezers are composed of only a pair of surface modified polydimethylsiloxane (PDMS) cantilevers. Since the front and back surfaces of the cantilevers have different wettability, they can be bent due to the difference of surface tension and hydrostatic pressure exerted on each surface when they come...
For the present study, we have successfully fabricated a novel cylinder-shaped device that is able to produce mono-dispersed plasma bubbles under atmospheric pressure and water environment. The generated plasma has characteristics of low temperature, which was generated by dielectric discharge barrier. Also, the plasma bubble has been successfully transported downstream with distance of 1.20 [cm].
