Plasmonics based sensors have been a prominent area of research. Plasmonics based sensors are widely used in bio sensing and many other applications. The basic mechanism in which these sensors operate is that there are metal nano particles that are separated by a very small distance between them. The dimensions of these nano particles is much smaller than the incident light [1]. For sensing pur...

background: nano-particles are extensively employed in most industries. several studies have been started to explore the probable detrimental effects of nano-particles on human reproduction. however, there is insufficient and controversially evident of effects of silver nano-particles on sperm parameters and other reproductive indices. objective: investigation of the effects of silver nano-part...

the potential use of nano technology for improving of withdrawal resistance of nail and screw in wood was evaluated. for this, the maintenance strength of nail and screw was measured under dry and wet conditions for poplar wood (populus nigra) coated with common paints in furniture industry and nano-particles. specimens with dimensions of 15×5×5 cm3 (l×r×t) were cut from poplar wood (populus ni...

This study examines the creation of a nano-featured biosensor platform designed for the rapid and selective detection of the bacterium Escherichia coli. The foundation of this sensor is carbon nanotubes decorated with gold nanoparticles that are modified with a specific, surface adherent ribonucleiuc acid (RNA) sequence element. The multi-step sensor assembly was accomplished by growing carbon ...

BACKGROUND Releasing drug molecules at the targeted location could increase the clinical outcome of a large number of anti-tumor treatments which require low systemic damage and low side effects. Nano-carriers of drugs show great potential for such task due to their capability of accumulating and releasing their payload specifically, at the tumor site. RESULTS FLT3 inhibitor - gold nanopartic...

Heated scallop-shell (HSS) nano-particles, prepared using a wet grinding mill, and microparticles were examined for their antibacterial activity against vegetative bacterial cells and spores. The median diameters of the nano-particles and micro-particles were approximately 20 nm and 30 µm, respectively. The antibacterial activity of HSS against Escherichia coli increased with an increase in con...

Gold doped TiO2 has been successfully synthesized via the photolysis method and is characterized by different techniques. NPs of gold doped TiO2 were utilized for the degradation of methylene blue as a material pigmentation pollutant. The substitution of Au on TiO2 surface was established via XRD, EDX, TEM, and FT-IR techniques. The TEM and SEM results appea...

zinc and iron nano-oxides (100 ppb) were promoted the hypericin and hyperforin production in hypericum perforatum cell suspension culture. high performance liquid chromatography method was used for detectection and identification of hypericin and hyperforin in h. perfuratum cell suspension cultures elicited with different concentrations of zinc and iron nano-oxide (0, 50, 100 and 150 ppb) after...

The nano-kinetics of colloidal particles and living cells with the colloidal particles were visualized by a newly developed video scope. The system of the new video scope has a feature of fine controlling the illumination conditions by using a single optical fiber. This characteristic enables one to obtain clear images of living cells and the motions of colloidal particles by light-scattering e...

This work presents simulation, analysis and implementation of morphology tuning of gold nano-island structures deposited by a novel convective assembly technique. The gold nano-islands were simulated using 3D Finite-Difference Time-Domain (FDTD) techniques to investigate the effect of morphological changes and adsorption of protein layers on the localized surface plasmon resonance (LSPR) proper...
