Electrical properties of silicon-based nanogap electrodes for label-free biomolecular detection
(American Scientific Publishers, 2013-02)
The electrical properties of 6-, 33- and 89-nm gap structures were systematically studied to evaluate the feasibility of these structures to be used in biomolecular sensing devices. The fabrication and morphological ...
A novel method for the synthesis of calcium carbonate (aragonite) nanoparticles from cockle shells
(Elsevier B.V., 2013-02)
We report a simple, novel and low-cost method for the synthesis of aragonite nanoparticles from cockle shells. Aragonite is one of the least abundant biogenic polymorphs of calcium carbonate and is widely used as a biomaterial ...
Sol-gel synthesis of ZnO nanorods for ultrasensitive detection of acetone
(American Scientific Publishers, 2013-12)
ZnO nanorods were synthesized on low cost thermally oxidized silicon substrate using a simple and easily performable sol-gel spin coating technique followed by hydrothermal growth. C-axis orientation, good crystalline ...
The electroosmosis mechanism for fluid delivery in PDMS multi-layer microchannel
(American Scientific Publishers All rights reserved., 2013-01)
Here we reported on fabrication of multi-layer microstructures that takes the advantage of electroosmosis to mix fluids. Microlaboratories for biochemical applications often require rapid mixing of different fluid streams. ...
Impact of hydrogen concentrations on the impedance spectroscopic behavior of Pd-sensitized ZnO nanorods
(Licensee Springer, 2013)
ZnO nanorods were synthesized using a low-cost sol-gel spin coating technique. The synthesized nanorods were consisted of hexagonal phase having c-axis orientation. SEM images reflected perpendicular ZnO nanorods forming ...
Sol-gel synthesis of Pd doped ZnO nanorods for room temperature hydrogen sensing applications
(Elsevier Ltd and Techna Group S.r.l., 2013-08)
A sol-gel spin coating technique was described for the synthesis of Pd doped ZnO nanorods for hydrogen sensing applications. The nanorods were hexagonal in shape, 50-100 nm in diameter and uniform in distribution. They ...
