Conjugation of DNA to Streptavidin-coated Quantum Dots for the Real-time Imaging of Gene Transfer into Live Cells

Kim J.K., Lim S.H., Lee Y., Shin Y.S., Chung C., Yoo J.Y., Chang J.K., Digital Bio Technology, Co, KR

We have developed the method for the conjugation of biotinylated DNA to streptavidin-coated quantum dots (QDs). QD-DNA conjugates and a highly sensitive fluorescence imaging technique are adopted to visualize gene transport across the membrane of [...]

Phase Morphology Control in Electrospun Nanofibers From Polymer Blends

Wei M., Kang B., Sung C., Mead J., University of Massachusetts-Lowell, US

Nanofibers of polybutadiene/polycarbonate blends were electrospun from polymer solutions. The effect of composition on the resulting internal morphology of the nanofibers was studied using Transmission Electron Microscopy (TEM). When the composition ratio of PB/PC blends [...]

Controlling the Photoactivity of Nanoparticles

Casey P., Boskovic S., Lawrence K., Turney T., CSIRO(CMIT), AU

The relative photoactivity of a series of nanophase ZnO powders with varying crystallite size (20-140nm) was determined using a chemical method based on the photobleaching behaviour of the stable radical 1,1-diphenyl-2-picrylhydrazyl (DPPH). It was confirmed [...]

Improved Reproducibility in Porous Silica Sol-Gel Processing Using Tertiary Butanol Solvent

Rissanen A.K., Blomberg M., Kattelus H., VTT Technical Research Centre of Finland, FI

Silica aerogels and xerogels are porous materials, which possess many exceptional properties. The research for the use of aerogel thin films in MEMS applications, such as humidity sensors, biosensors and calorimetric devices, is still at [...]

The Measurement of Ferroelectric Thin Films Using Piezo Force Microscopy

Cain M.G., Dunn S., Jones P., National Physical Laboratory, UK

The use of Atomic Force Microscopy to evaluated the surface properties of ferroelectric thin films is often associated with poor signal to noise ratio images and quantitative analysis is not possible. In this presentation the [...]

Sol-gel Silane Films for DNA Microarray Experiments

Saal K., Tätte T., Kink I., Kurg A., Lõhmus A., Lõhmus R., Mäeorg U., Rinken A., Lõhmus A., Lõhmus R., University of Tartu, EE

Aim of the current research is development of a method for producing a new kind of aminosilanized films suitable for applications utilizing immobilized DNA molecules. We report on new progress in a procedure proposed in [...]

Metrology Development for the Nanoelectronics Industry at the National Institute of Standards and Technology

Dagata J.A., Richter C.A., Silver R.M., Vogel E., Martinez de Pinillos J.V., NIST, US

The National Institute of Standards and Technology has provided and continues to provide critical metrology development for the semiconductor manufacturing industry as it moves from the microelectronic era into the nanoelectronic era. This presentation will [...]

Properties of Self-Assembled Monolayer as an Anti-adhesion Layer on Metallic Nano Stamper

Choi S., Lee N., Kim Y.J., Kang S., Yonsei University, KR

The increasing demand for micro/nano optical components in the fields of optical data storage, optical communication, and digital display has required mass replication of polymeric micro/nano patterns. In nano replication process, surface quality can be [...]

Coating Growth on Nanofibers: Multi-Scale Modeling, Simulations and Experiments

Buldum A., Clemons C., Evans E.A., Kreider K.L., Young G.W., The University of Akron, US

Theoretical and experimental investigations on nanoscale deposition technology are critical for nanoscale materials research and for future nanodevice applications. Moreover, because of the varied and coupled physical phenomena involved (mechanical, electromagnetic, chemical, thermal, etc.), the [...]

Morphology of Nanostructured Films Synthesized via Electrodeposition

Magan R.V., Sureshkumar R., Washington University, US

In this study we perform Brownian dynamics simulations to investigate the influence of surface reaction rate on the development of size dispersion of interfacial nanostructures that form by electrodeposition of non-interacting ions (particles) onto surfaces [...]
