Ultrathin, hyperelastic PDMS nano membrane : Fabrication and characterization

초록

In this study, we fabricated ultrathin and hyperelastic polydimethylsiloxane(PDMS) nano membranes with various thicknesses and sizes by using PDMS diluted with hexane, sacrificial layer and PDMS block. We used these membranes to study the characteristics and possibilities of applying as a cell device such as lung on a chip. [1] We discovered that this free standing PDMS nano membrane is so elastic and thin that it is sufficiently permeable to air and methanol. We also investigated the usage as a cell device by culturing lung cells on the membrane.[2] Copyright © (2011) by the Chemical and Biological Microsystems Society.
