Nanoporous Alumina Membranes Based Microdevices for Ultrasensitive Protein Detection

Bothara M.G., Reddy R.K., Barrett T., Carruthers J., Prasad S., Portland State University, US

This research focuses on using the electrical and chemical properties of nanoporous alumina membranes to improve the sensitivity and performance of Si-based microdevices for protein sensing. The integration of nanoporous membranes with the microdevice results [...]

Growth and Engineering of High Aspect-Ratio AAO Templates Integrated on Silicon Substrates

Choi S., Daugherty M., Enable IPC Corporation, US

We have developed a CMOS-compatible process for manufacturing nanowires directly on silicon (or other) substrates. This process removes some of the steps for conventional nanowire manufacture. The result are highly-ordered, high aspect-ratio nanowires for use [...]

II-VI Semiconductor Quantum Wire Fabrication and Application to IR Detection

Crouse D.T., Crouse M., Crouse D.T., Crouse M., Mahapatra S., Ikram A.A., City College of New York, US

A nanoporous alumina template has been developed that provides a practical and flexible method of fabricating semiconductor and metal nanowires on any desired substrate. In situ electrochemical techniques are used to transform this multilayer precursor [...]

Nanoparticle Dispersions for Polishing Applications

Murray P.G., Nanophase Technologies Corporation, US

Increasingly, improvements in surface roughness and planarity are being sought in a variety of technologically advanced polishing applications related to the electronics industry. From the production of photomask blanks to the fabrication of microelectronic memory [...]

A Disposable Glucose Biosensor Based on Diffusional Mediator Dispersed in Nanoparticulate Membrane on Screen-Printed Carbon Electrode

Gao Z., Xie F., Shariff M., Arshad M., Ying J.Y., Institute of Bioengineering and Nanotechnology, SG

In this paper, we described a disposable glucose biosensor based on co-dispersion of a diffusional polymeric mediator and glucose oxidase (GOX) in nanoparticulate membrane on screen-printed carbon electrode. The biosensor exhibited classical features of a [...]

Nanostructuring of Surfaces using Anodic Alumina Masks – Methods, materials and properties

Sawitowski T., Beyer N., Wagener S., Schulz F., AlCove Surfaces GmbH, DE

Since the discovery that cleanability is not necessarily linked to smoothness or gloss of surfaces it is interesting to take a closer look at methods allowing surfaces to be structured on a micrometer and nanometer [...]
