Extremely Stretchable Electrode based on Combination of Inkjet-Printed Silver and Conductive Composite for Stretchable Lighting Applications

Kim D., Kim S., Byun J., Chung S., Kim D., Kim S., Hong Y., Seoul National University, KR

We have studied stretchable electrode based on combination of inkjet-printed silver electrode and conductive composite materials for stretchable lighting device applications. Previous stretchable electrodes were mainly realized by either vacuum deposition or inkjet-printing of conductive [...]

Scanning probe-based fabrication of 3D nanostructures via affinity templates, functional RNA and meniscus-mediated surface remodeling

Chung S., Presley A.D., Elhadj S., Hok S., Hah S.S., Chernov A.A., Francis M.B., Eaton B.E., Feldheim D.L., DeYoreo J.J., Lawrence Berkeley National Laboratory, US

Developing generic platforms to organize discrete molecular elements and nanostructures into deterministic patterns at surfaces is one of the central challenges in the field of nanotechnology. Here we review three applications of the atomic force [...]

Active Sealing for Soft Poymer Microchips

Bang H., Lee J., Lee W.G., Park J., Yun H., Lee J., Lee W.G., Chung C., Chung S., Cho K., Chung C., Chung S., Han D-C, Chang J.K., Seoul National University, KR

This paper presents a universal sealing method for soft polymer (elastomer) microchips. A robust and reversible sealing method which allows various materials to be bonded and sealed tightly with each other even in aqueous solutions, [...]

Highly Efficient Electro-permeabilization of Mammalian Cells Using Micro-electroporation Chip

Shin Y.S., Kim J.K., Lim S.H., Lee Y., Lee Y.K., Cho K., Lee Y., Lee Y.K., Chung C., Chung S., Chung C., Chung S., Han D-C, Chang J.K., Seoul National University, KR

Electroporation, is widely used method that can be directly applied to the field of gene therapy. However, very little is known about the basic mechanisms of DNA transfer and cell response to the electric pulse. [...]

Microfabricated Fluorescence-Activated Cell Sorter with Hydrodynamic Flow Manipulation

Bang H., Chung C., Chung S., Kim J.K., Kim S., Kim J.K., Kim S., Chung C., Chung S., Han D-C, Chang J.K., School of Mechanical & Aerospace Eng., Seoul National University, KR

Presented is a novel flow manipulation and particle detection method for the microfabricated fluorescence-activated cell sorter (FACS). With hydrodynamic flow manipulation which includes passive flow channeling and hydrodynamic actuation with nozzle flow, we have developed [...]
