Nanobiosensor for the detection and quantification of specific DNA sequences in degraded biological samples
(Springer-Verlag, 2011-06-20)
A 27-nucleotide AluI fragment of swine cytochrome b (cytb) gene was integrated to a 3-nm diameter citrate- tannate coated gold nanoparticle to fabricate a species specific nanobiosensor. The biosensor was applied to ...
A review on the electrochemical sensors and biosensors composed of nanogaps as sensing material
(National Institute of Research and Development for Optoelectronics, 2010)
In the past two decades, the biological and medical fields have seen great advances in the development of biosensors and biochips capable of characterizing and quantifying biomolecules.To understand the important relationship ...
A silicon-oxide-silicon vertically separated electrode nanogap device structure
(American Institute of Physics, 2009-06-01)
In this study, we present a simple method to form a nanogap between two silicon contacts separated by a thin oxide gap. We also demonstrate the validity of dielectric spectroscopy results of two wafer samples (different ...
Nanoparticle sensor for label free detection of swine DNA in mixed biological samples
(IOP Publishing Ltd., 2011-05-13)
We used 40 5nm gold nanoparticles (GNPs) as colorimetric sensor to visually detect swine-specific conserved sequence and nucleotide mismatch in PCR-amplified and non-amplified mitochondrial DNA mixtures to authenticate ...
MOS Transistor Mask Design Using SEM Based E-Beam Lithography
(Malaysian Invention & Design Society (MINDS), 2006-05-19)
Electron beam lithography (EBL) is one of the alternative tools in transferring micro and nano circuit patterns from design editor to the substrate. EBL is state-of-the-art technology for micro and even to nano feature ...
CdS film thickness characterization by R.F. magnetron sputtering
(American Institute of Physics, 2009-06-01)
In this work, cadmium sulphide (CdS) target with 99.999% purity was used as a target in RF magnetron sputtering. The sputtering experiment was conducted onto silicon oxide substrates at different temperatures ranging from ...
Nanoparticle sensor for label free detection of swine DNA in mixed biological samples
(IOP Publishing Ltd, 2011-05-13)
We used 40 ± 5 nm gold nanoparticles (GNPs) as colorimetric sensor to visually detect swine-specific conserved sequence and nucleotide mismatch in PCR-amplified and non-amplified mitochondrial DNA mixtures to authenticate ...
Nanowire formation using electron beam lithography
(American Institute of Physics, 2009-06-01)
Miniaturization and performance improvements are driving the electronics industry to shrink the feature size of semiconductor device. Because of its diffraction limit, conventional photolithography is becoming increasingly ...
Selective growth of ZnO nanorods on microgap electrodes and their applications in UV sensors
(Springer, 2014-01)
Selective area growth of ZnO nanorods is accomplished on microgap electrodes (spacing of 6μm) by using a facile wet chemical etching process. The growth of ZnO
nanorods on a selected area of microgap electrode is carried ...
A brief review of the current technologies used for the fabrication of metal-molecule-metal junction electrodes
(Scientific.Net, 2012-12)
Fabrication techniques for Metal-molecule-metal junction electrodes suitable to study electron tunneling through metal junctions are reviewed. The applications of current technologies such as mechanical break junction, ...
