Different contribution of carbon nanotubes and graphene oxide in single nucleotide polymorphism for the diagnosis of human mad-cow disease

Choi W., Lee J-H., Luminescent MD, LLC, US

Rapid single nucleotide polymorphism (SNP) with 1,1’-oxalylimidazole chemiluminescence (ODI-CL) detection was developed for the early diagnosis of human mad-cow disease. Mutated single strand DNA (ssDNA) sequence discovered from patients having human mad-cow disease rapidly hybridize [...]

Polarization controllable laser-induced ripple structure in dye-doped liquid crystal films

Yu K-Y, Huang B-Y, Kuo C-T, National Sun Yat-San University, TW

The laser-induced ripple structure of dye-doped liquid crystals has been investigated with the various polarization of pump beam. The process of laser-induced ripple structure involves two stages, the dye adsorption on substrate and the ripple [...]

Novel, Flexible and Low-power Driven AC Electroluminescent Lamp from Carbon Nanotube Embedded Phosphor Material

Haranath D., Yadav D., Sahai S., Shanker V., CSIR-National Physical Laboratory, IN

 We present a novel, cost-effective and simple technique operable at room temperature, wherein a non-electroluminescent (non-EL) material is being converted to exhibit stable and efficient EL using CNTs.  The role of CNT has [...]

Flexible Nanoporous Anodic Aluminum Oxide(np-AAO) Template Coated with Self-Assembled Au Nanocrown Array for Photonic Switches

Hong C., Shew B.Y., National Synchrotron Radiation Research Center (NSRRC), TW

This study reports a nanoporous anodic aluminum oxide (named np-AAO) template coated with Au nanocrown array on PET substrate for photonic switching application (Fig.1). In this device, the Au nanocrown array for photonic switching are [...]

Combination of magnetic and non-magnetic graphene oxide to develop chemiluminescent aptasensor capable of rapidly quantifying tumor markers

Choi H-K, Park L., Kim J., Lee J-H., Luminescent MD, LLC, US

Rapid and sensitive chemiluminescent aptasensor capable of rapidly sensing tumor markers in human serum with the combination of magnetic and non-magnetic graphene oxide. Human serum (150 µl) containing tumor markers (e.g., AFP and PSA) was [...]

Background free biosensor using the combination of graphene oxide and Fe3O4 nanoparticles

Cho S., Park L., Chung R., Lee J-H., Luminescent MD, LLC, US

Cost-effective and rapid biosensor with background free chemiluminescence (CL) detection was developed using ssDNA aptamer-conjugated 6-FAM fluorescein (DAF), graphene oxide bound with magnetic nanoparticle (GMN), and 3,4,5-trimethoxyphenylglyoxal (TMPG). When thrombin was incubated in TE buffer [...]

Synthesis and Magnetic Properties of Double Perovskite La2BMnO6 (B = Ni or Co) Nanoparticles

Mao Y., Parsons J.G., McCloy J.S., University of Texas-Pan American, US

Double perovskite oxides with the general formula AA’BB’O6 (where A and A’ are rare earth or alkaline earth metals, and B and B’ are d-block transition metals) display a wide variety of interesting physical properties [...]

The manifestation of the one-dimensional non-collinear spin-dependent scattering on magnetized nano-element structures

Sahakyan A.S., Movsesyan R.M., Kocharian A.N., California State University Los Angeles, US

The transfer-matrix approach is used to investigate the scattering of spin-polarized electron and neutron waves on the simple magnetized nanoelement structures which energetic profiles presents a finite potential magnetic barrier, in particular, of rectangular form. [...]

Granular magnetoresistance effects in systems with organic matrices

Meyer J., Schäfers M., Rempel T., Hütten A., Bielefeld University, DE

The granular giant magnetoresistance effect was originally studied in systems with ferromagnetic granules embedded in a metallic matrix. In contrast to previous systems, we have tested conductive nonmagnetic gels as matrices for the Co nanoparticles. [...]

A Novel Silicon Nanowire-based Electron Detector Utilized in Scanning Electron Microscopes

Hajmirzaheydarali M., Akbari M., Mohajerzadeh S., University of Tehran, IR

Electron microscopes are the scientific tools which utilize highly energetic electron beam to overcome the light limitations in the study of specimen in nm scale. Electron detection has an important role in microscopic analysis and [...]
