Electrostatic Induced Inkjet Printing System for Micro Patterning and Drop-On-Demand Jetting Characteristics

Choi J., Kim Y., Kim Y.J., Son S.U., Kim Y., Kim Y.J., Lee S., Byun D., Ko H.S., Sungkyunkwan University, KR

Printing technology is considered to be a key technology even in the field of electronics, materials processing, and bio applications. Inkjet printing is an interesting patterning technique for electronic devices because it requires no physical [...]

One-step Target Protein detection from Whole Blood in a Lab-on-a-Disc

Lee B-S, Lee J-G, Lee J.N., Lee B-S, Lee J-G, Lee J.N., Lee B-S, Lee J-G, Lee J.N., Park J.M., Cho Y-K, Kim S., Ko C., Samsung Advanced Institute of Technology, KR

We report a fully integrated, one-step Lab-on-a-Disc for detecting target protein from whole blood utilizing centrifugal microfluidics, so called “Immunoassay Lab-on-a-Disc”. The design principle is the microbead-based sandwich ELISA on the Disc. The microbeads are [...]

One-step White Blood Cell Separation from Whole Blood

Park J.M., Kim B.C., Lee J-G, Samsung Advanced Institute of Technology (SAIT), KR

Isolation of White Blood Cells (also called “WBC”) from whole blood is a first very important step for many in vitro assays. One currently accepted technique for WBC separation, referred to as the conventional manual [...]

Feasibility Study of Cochlear-like Acoustic Sensor using PMN-PT Single Crystal Cantilever Array

Hur S., Lee S.Q., Kim W.D., Korea Institute of Machnery & Materials, KR

The mammalian cochlea is an organ that performs the conversion of the incoming mechanical energy into electrical signals in the auditory nerve fibers. Current cochlear Implants have been developed in an effort to restore sensorineural [...]

Fabrication of Nanoparticle Embedded Polymer Nanorod by Template Based Electrodeposition

Kang S-W, Kang W-S, Nam G-H, Kim H-S, Kim J.H., Kim K-J, Kim H-S, Kim J.H., Kim K-J, Kang S-W, Kang W-S, Kim H-S, Kim J.H., Kim K-J, Ajou University, KR

Inorganic semiconductor materials in nano-dimension have drawn intense attention in recent years because of their size-tunable optoelectronic properties arising from the quantum confinement effect. These materials often require to be incorporated into other materials, often [...]

Multi-Bit/Cell SONOS Flash Memory with Recessed Channel Structure

Han K-R, Kwon H-I, Lee J-H., Kyungpook National University, KR

A novel device structure for 4-bit/cell with recessed channel structure is presented and characterized for NOR-type nonvolatile memory (NVM) technology. In this paper, we studied a 4-bit/cell SONOS flash memory cell Since two transistors in [...]

Atomistic Simulation on Boron Transient Diffusion during in Pre-amorphized Silicon Substrate

Park S.Y., Cho B-G, Won T., Inha University, KR

We investigated the boron diffusion in the silicon posterior to PAI (pre-amorphization implant) in order to understand the mechanism for amorphization process and generation-recombnation of defects. Silicon atoms were weighed as a new pre-amorphization implant [...]

Novel Approach for Preparation of Organic-Inorganic Hybrid Nanocomposites

Kim I-J., Kwon K.H., Cheil Industries Inc., KR

Novel organic-inorganic hybrid nanocomposites were synthesized through emulsion grafting polymerization in the presence of silica particles coated with methacryloxy(propyl)trimethoxysilane. Well-defined polymer chains were grown from the nanoparticle surfaces to yield individual particles composed of a [...]

Real-time detection of neurotransmitter using enzyme-immobilized CNT network transistors in 11 vessel occlusion rat model

Lee G.J., Lim J.E., Park H.J., Park H.K., Park J.H., Eo Y.H., Kim B.S., Park H.J., Park H.K., Park J.H., Choi S.K., Hong S., Park H.J., Park H.K., Park J.H., Kyung Hee University, KR

The field effect transistor (FET) made of carbon nanotube (CNT) can be used as sensor due to their extreme sensitivity to local chemical environments. Glutamate is the principal excitatory neurotransmitter in the brain, and its [...]

Identification of PCR Product by double-strand DNA Denaturation using Label-free Field-effect Transistor

Han J., Chung W., Yoo K., Shim J., Samsung Advanced Institute of Technology, KR

We demonstrate an innovative method of PCR product identification that is based on thermal denaturation of PCR products which are immobilized on microbeads using integrated BioFET. Purification step was finished simply by capturing the biotinylated [...]
