Preparation of ion group functionalized diblock copolymers and examination of their thermogelling properties

Lee B.K., Kwon D.Y., Kwon J.S., Park J.H., Kwon D.Y., Kwon J.S., Kim J.H., Kim M.S., Oh S.H., Kim J.H., Kim M.S., Ajou University, KR

To investigate thermogelling behavior, in this study, methoxy polyethylene glycol-b-[poly(ε-caprolactone)-ran-poly(6-chloride-ε-caprolactone) (PCL-ran-PfCL)] (PCL-Cl) diblock copolymers were designed such that the PfCL content in the PCL segment was varied. The PCL-Cl diblock copolymers were derivatized by introducing [...]

Phosphate recognition using multilayer charged thin films containing zirconium (Zr) ions for biochip applications

Lee M., Kim J.H., Kim N., Kim S-H, Kim J.H., Kim N., Kim S-H, Shin C.-J., Koh K., Kim J.H., Kim N., Kim S-H, Ajou University, KR

The phosphate residue plays an important role as not only the structural component of DNA and lipid but also the activation signal of protein in the cellular signaling pathways. Therefore, the selective recognition for the [...]

Large area, directionally aligned single-walled carbon nanotube thin film by self-assembly and compressed sliding methods

Najeeb C.K., Lee J-H., Chang J., Kim J.H., Ajou University, KR

To fabricate large area directional arrangement of SWNTs, we employed two different methods such as self assembly of surface modified SWNTs by drop casting or spin coating and by compressed sliding of SWNT dispersion between [...]

High resolution imaging of biological materials using hydrophobic carbon nanotube AFM probes

Lee J-H., Najeeb C.K., Chang J., Kang W-S, Nam G-H, Kim J.H., Ajou University, KR

Carbon nanotube (CNT) tipped atomic force microscope (AFM) probes have shown a significant potential for obtaining high resolution imaging of nanostructure and biological materials. In this work, we report a simple method to fabricate single-walled [...]

Fabrication of Nanoparticle Embedded Polymer Nanorod by Template Based Electrodeposition

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 [...]

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

Kim H-S, Kim J.H., Kim H-S, Kim J.H., Ko S-H., Cho Y-J, Kim H-S, Kim J.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 [...]

Au Nanoparticle Coupled- Surface Plasmon Resonance Chemical Sensor for Sensitivity Enhancement

Kim H-S, Kim J.H., Choi S-W, Kim H-S, Kim J.H., Cho Y-J, Choi S-W, 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 [...]
