A Markedly Cntrollable Adhesion of Superhydrophobic Sponge-like Nanostructure TiO2 Films

Lai Y., Lin C., Huang J., Zhuang H., Sunb L., Nguyen T., Xiamen University, CN

A method consisting of electrochemical anodization and self-assembling of hydrophobic-hydrophilic mixture has been employed to fabricate superhydrophobic sponge-like nanostructured TiO2 surfaces with remarkably controllable adhesion. Water adhesion ranged from ultra-low (5.0 N) to very high [...]

Ultra-sensitive Electrochemical Detection of E. coli Using Nano-porous Alumina Membrane

Mishra N.N., Maki G., Maki W.C., Filanoski B., Fellegy M., Cameron E., Rastogi S.K., Maki G., Maki W.C., University of Idaho, US

A combinational method has been developed for ultra-sensitive detection of E. coli. The method combined biological, nano-fabrication and electrochemical techniques to achieve highly specific and ultra-sensitive detection of bacterial pathogen. E. coli K12 was used [...]

Electrochemical Characteristics of Nanotube Formed Ti-Zr Alloy

Kim W.G., Choe H.C., Ko Y.M., Brantley W., Chosun University, KR

In this paper, Ti-Zr(10, 20, 30 and 40 wt%) alloys were prepared by arc melting and nano-structure controlled for 24 hr at 1000 °C in argon atmosphere. Formation of oxide nanotubes are conducted by anodizing [...]

Novel Method for the Electrochemical Synthesis of Nickel-Rich Oxide Nanowires

Thorne S.A., Bhargava Y.V., Mintz T.S., Radmilovic V., Suzuki Y., Devine T.M., University of California-Berkeley, US

Using a novel electrochemical process, functionalized and self-assembled Ni-rich oxide nanowires were grown from an Alloy 600 (Ni – 15.5 a/o Cr, 8a/o Fe) substrate. The formation of the nanowires occurs in a high-temperature (238-288 [...]

Micro-Patterning of Ionic Reservoirs within a Double Bilayer Lipid Membrane to Fabricate a 2D Array of Ion-Channel Switch Based Electrochemical Biosensors

Sansiñena J.M., Yee C.K., Sapuri A., Swanson B.I., Redondo A., Parikh A.N., Los Alamos National Laboratory, US

We present a simple approach for the design of ionic reservoir arrays within a double phospholipid bilayer to ultimately develop a 2D array of ion-channel switch based electrochemical biosensors. As a first step, a primary [...]

High-Resolution Electrochemical In Situ Printing

Egeland R.D., Southern E.M., Oxamer & Oxford Gene Technology, UK

This work demonstrates a new method for making oligonucleotide microarrays by synthesis in situ. The method uses conventional DNA synthesis chemistry with an electrochemical deblocking step. Acid is delivered to specific regions on a glass [...]

Nanoscale Bio-Molecular Control Using EC-OWLS

Bearinger J.P., Vörös J., Spencer N.D., Hubbell J.A., Textor M., ETH Zürich/ Lawrence Livermore National Laboratory, US

A new technique has been developed that combines evanescent-field optical sensing with electrochemical control of surface adsorption processes. This technique, termed Electrochemical Optical Waveguide Lightmode Spectroscopy (EC-OWLS), proved efficient in monitoring molecular surface adsorption and [...]
