Biological effects of PLA-TCP nanocomposites on osteoblastic cells

Kim H.W., Kim J.W., Kim T.I., Lee H.-H., Lee S.-P., Kim H.W., Kim J.W., Kim T.I., Kim H.W., Kim J.W., Kim T.I., Lee H.-H., Lee S.-P., Seoul National University, KR

Composite substrates are considered as prospective matrix to populate and support cells in the bioengineering field. Synthetic degradable biomaterials, including poly(lactic acid) (PLA) and tricalcium phosphate (TCP), are widely used for matrix scaffold. In present [...]

Investigation of optimal separation condition in negative dielectrophoresis force based particle sorting platform

Lee J-H., Kim B-K., Kim Y.H., Kim B-K., Kim Y.H., Kim B-K., Kim Y.H., Korea Aerospace University, KR

we investigate an optimal separation condition regarding the gravitation, the hydrodynamic force and the n-DEP force acting on particles in the sorting platform since contribution of each force is the main parameter to determine SE. [...]

Fabrication of ITO/Gold nanoparticle/RGD peptide Composites to Enhance Electrochemical Signals from Human Neural Stem Cells

Kim T-H., Choi J.W., Sogang University, KR

Gold nanoparticles (GNP) and RGD peptide modified indium tin oxide (ITO) electrode was fabricated to enhance the electrochemical signals from neural stem cells (HB1.F3). ITO film is well-known transparent and conductive material suitable for both [...]

Capacitance-based real time monitoring of endocytosis

Lee R.M., Kim D., Kim K-M, Kim K., Kim P., Kim D., Kim K-M, Kim K., Kim P., Kim D., Kim K-M, Kim K., Kim P., Kim D., Kim K-M, Kim K., Kim P., Yun C.O., Shin J.-S., Yoo K.H., Yonsei University, KR

There exist three kinds of endocytosis; receptor mediated endocytosis, pinocytosis and phagocytosis. First, receptor-mediated endocytosis is essential for targeted gene/drug delivery to a specific cell type. Second, pinocytosis is the engulfing and digestion of dissolved [...]

Nano-ELISA using gold nanoparticle-DNA complex for the detection of pathogenic microbe

Kim H-S, Oh B.-K., Sogang Univeristy, KR

In this study, we report on the rational design of a nano-complex that consists of gold nanoparticle (AuNP), antibody, oligonucleotides and horseradish peroxidase (HRP) for the detection of pathogen. The AuNP was functionalized with a [...]

Microfluidic Neural Cell Chip for Monitoring of PCBs

Park S., Kim Y.K., Hankyong National University, KR

Rapid and reliable monitoring of persistent organic pollutants (POPs) is very important to prevent their harmful effect on environment. In this study, microfluidic device to detect polychlorinated biphenyls (PCBs), which are well known insecticide, was [...]

A DNA sensor using gold-coated barcode silica nanotubes

Kim S.Y., Jun S.J., Min J., Kyungwon University, KR

A DNA senor using silica nanotubes (SNTs) was developed to detect some bacteria by barcoded SNTs. The SNTs were fabricated using anodic aluminum oxide (AAO) templates by the surface sol-gel method. To recognize each DNA [...]

Numerical Study on the Mixing Performance of Ring-Type Electroosmotic Micromixer with Configurations of Obstacle in the Mixing Chamber

Seo H.S., Kim Y.J., Sungkyunkwan University, KR

Rapid and efficient mixing is important for many microfluidic applications but challenging process in many microfluidic systems that perform complex chemical synthesis and analysis. Most existing microfluidic mixing systems are limited to low Reynolds number [...]
