A Study of Inorganic-Polymer Hybrid Films for Various Surface Functionalization

Park B-S., Lui Z., Jin H.S., Yang S.-Y., Chungnam National University, KR

The PEM coatings were applied on magnetic particles and the deposited films were examined by zeta-potential analysis and fluorescence microscope. Additionally, we utilized layer-by-layer deposition method to modify the surface of the micro-channel of the [...]

Ultra-thin Nanocomposite Membranes for Highly Sensitive Sensors

Kang T.J., Jang E.Y., Lee J-H., Kim Y.H., Seoul National University, KR

Highly sensitive sensor arrays are critical for prospective devices and demanded for various applications. Measuring microscopic deflections with sensitive membranes is one of the most versatile approaches for pressure, acoustic, chemical and biomolecular sensing. Here [...]

Dynamics and distribution of counterions in the vicinity of a flexible polyelectrolyte

Lo T.S., Khusid B., Koplik J., Acrivos A., New Jersey Institute of Technology, US

Transport properties of polyelectrolytes in solution, such as electrophoretic mobilities, are strongly related to the distribution of the counterions in the vicinity of the molecules. When the charge density of the polyelectrolyte is above a [...]

Polymer-based gene delivery system fabricated with the participation of a polyanion

Sun Q., Stolnik S., University of Nottingham, UK

A DNA/polycation/polyanion system is being designed, which is supposed to be a potentially improved system in comparison to the traditional gene delivery system (DNA/polycation system). The production of such a DNA/polycation/polyanion system is based on [...]

Corrosion Protection by Multifunctional Stratified Coatings

Westcott S.L., Kotov N.A., Ostrander J.W., Mamedov A.A., Reust D.K., Roark J.P., Nomadics, Inc., US

We have demonstrated a hybrid coating consisting of both a stratified layer that incorporates corrosion inhibiting ions and a silicate barrier layer. The stratified layer is applied to the aluminum alloy using the layer-by-layer assembly [...]
