Synthesis and characterization of copper oxide decorated zinc oxide nanorods

Hong S.H., Hwang S.H., Kim H-S, Kim S., Lee D.J., Lim S.K., DGIST(Daegu Gyeongbuk Institute of Science & Technology), KR

One-dimentional nanostructures in the form of nanorods, nanowires, nanofibers or nanotubes, appear as an exciting research area for their great potential of applications. Zinc oxide is an n-type semiconductor that has been well known for [...]

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 [...]

Fabrication of Nanoparticle Embedded Polymer Nanorod by Template Based Electrodeposition

Kang S-W, Kang W-S, Kim H-S, Kim J.H., Kim K-J, Nam G-H, 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 [...]

Chip-Based Energy Transfer System between Quantum dots and Gold Nanoparticles for Analysis of Protein Glycosylation

Kim H-S, Kim Y.P., Oh E., Oh Y.H., Park S., KAIST, KR

Protein glycosylation is one of the most essential processes in the living systems, and often is a major target for developing therapeutics and diagnosis. We have developed a chip-based energy transfer system between quantum dot [...]

Multiplexed Proteolytic Enzyme Assay Based on Energy Transfer between Quantum Dots and Gold Nanoparticles

Kim H-S, Kim Y.P., Oh Y.H., Korea Abvanced Institute of science and Technology, KR

Proteases are key enzymes that regulate both normal and malignant tumor progress. Evaluating these enzymes and their inhibitors, therefore, has a great potential to diagnostics or therapeutic treatment against specific diseases or disorders. We have [...]

Au Nanoparticle Coupled- Surface Plasmon Resonance Immuno-sensor for Sensitivity Enhancement

Cho Y-J, Kim H-S, Kim J.H., Ko S-H., Ajou University, KR

In order to overcome the sensitivity limitation of SPR, nanoparticle-coupled SPR biosensors have explored since nanoparticles may significantly enhance the sensitivity by 1-2 orders of magnitude. Although the nanoparticle conjugated method contributes to the enhancement [...]

Cho Y-J, Choi S-W, Kim H-S, Kim J.H., Ajou University, KR

In order to overcome the sensitivity limitation of SPR, nanoparticle-coupled SPR biosensors have explored with tremendous interests since nanoparticles may significantly enhance the sensitivity by 1-2 orders of magnitude. M. J. Natan et al. reported [...]

Fast and Easy Detection System of Protein Glycosylation by Using Resonant Energy Transfer between Nanoparticles

Kim H-S, Lee D., Oh E., Korea Advanced Institute of Science and Technology, KR

We construct the new glycosylation detection system using Resonance Energy Transfer (RET) between gold nanoparticles (AuNPs) and semiconductor quantum dots (QDs). RET can be induced by biomolecular interactions between concanavalin A (conA)-conjugated AuNP (conA-AuNP) as [...]

A Simple and Direct Biomolecule Detection Based on a Microwave Resonator
