Ionic liquid: an innovative medium for nanofabrication

Darwich W., Santini C.C., Gaillard F., Haumesser P.-H., université de lyon 1, CNRS UMR 5265, FR

Porous silicon (PSi) has been attracting a great attention as a breakthrough material with exceptional characteristics for microelectronics, layer transfer technology, solar and fuel cells, biomedicine, etc. Its properties can be modified by in introducing [...]

Investigations on Transmembrane Ion Channels Suspended over Porous Silicon Membranes

Tantawi K.H., Berdiev B., Cerro R., Williams J.D., University of Alabama in Huntsville, US

This article presents a batch-fabricated porous silicon membrane tool used to investigate transmembrane protein functionality in complex biological systems. We address the physical and chemical requirements fabricate the thin porous membrane, attached a lipid bilayer, [...]

Fabrication of complex three-dimensional multilevel silicon micro- and nano-structures

Azimi S., National University of Singapore, SG

We have developed a new process to fabricate arbitrary-shaped, multilevel, three-dimensional free-standing micro- and nano-structures on bulk silicon using focused high energy proton beam irradiation, followed by electrochemical anodization. We make use of the fact [...]

Electrosynthesis of Intrinsically Conducting Polymers/Silicon Nanocomposites: Formation Mechanism and Optical Properties

Harraz F.A., Salem A.M., Central Metallurgical R&D Institute (CMRDI), EG

When a silicon wafer is subjected to electrochemical etching in fluoride-based solution, silicon surface develops pores, often called porous silicon (PSi). A variety of pore sizes ranging from a few nanometers up to a few [...]

Enhanced bioavailability of peptide YY using nanoporous silicon as a drug carrier

Kovalainen M., Monkare J., Makila E., Salonen J., Lehto V-P, Herzig K-H, Järvinen K., University of Turku, FI

Biomedical applications of inorganic nanomaterials have been actively investigated during the last years. Porous silicon (PSi) is one of those new promising materials possessing several attractive properties. It is biodegradable and considered to be safe [...]

Superhydrophobic porous silicon surfaces

Bolognesi G., University of Roma “La Sapienza”, IT

In this paper, we present a novel inexpensive technique to produce superhydrophobic surfaces from porous silicon. Superhydrophobic surfaces are a key technology for their ability to reduce friction losses in microchannels and their self cleaning [...]

Copper Displacement Deposition on Nanostructured Porous Silicon

Bandarenka H., Redko S., Nenzi P., Balucani M., Belarusian State University of Informatics and Radioelectronics, BY

In the present work we have demonstrated nanosized structures fabrication by the copper displacement deposition on electrochemically etched porous silicon. Peculiarity of such method is the convergence of copper reduction with porous silicon dissolution. Principal [...]
