Result In the experiment‚ Silver nanoparticles is used as it has low absorption losses‚ compared to other metals. The formation of silver nanoparticles is done by depositing of various mass thickness of uniform layer of silver at the rate approximately 2 Å/ s at 1x10−5 Torr. After this‚ the sample were annealed in nitrogen for 50 min at 200 °C. The particle coalesce together to formed island due to surface tension. In this experiment‚ four samples were used‚ a) 1.25 µm SOI Test Cells – The thickness

Place‚ Singapore Abstract A low-cost‚ simple‚ rapid and selective nucleic-acid based lateral flow strip biosensor (LFSB) for possible dengue viral RNA detection is described in this study. The detection is based on competitive binding‚ where gold nanoparticles (AuNPs)‚ with average size of ~10 nm confirmed using UV-Vis‚ TEM and AFM images‚ are used as visualizing agents. These are bioconjugated with DNA which competitively binds with its complementary strand either in the sample or in the test line of

CaCO3 nanoparticles due to increased interfacial contact area and enhanced interfacial adhesion between CaCO3 nanoparticles and PVC matrix. Titanate treated nano-CaCO3/PVC composites had superior tensile and barrier performance compared to those of untreated nano-CaCO3/PVC composites‚ while the transparency of the film was retained.

) were investigated by Fourier transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA). The size distribution of the TiO2 nanoparticles was measured using transmission electron microscope and scanning electron microscope. The studies on the mechanical properties of composite material indicate that the addition of TiO2 nanoparticles increases its strength. The prepared nanocomposite dressing has excellent antimicrobial efficacy and good biocompatibility against NIH3T3 and L929

in medicine. One application is employing nanoparticles to deliver drugs and other substances to cancer cells. Particles are engineered to attach to the cancer cells directly. Ethylene glycol molecules are used to stop white bloods cells to attack the nanoparticles therefore increasing the circulation time in the human body. Once the cancer cell is located the payload is delivered or alternatively‚ X-ray is used to activate the electrons of the nanoparticle to destroy the tumor. (Nanotechnology in

Pollutants in the atmosphere but can also be found in many household items like detergents that contain surfactants and nanoparticles. Surfactants are used for cleaning and solubilization properties within detergent. The hydrophobic and hydrophilic characteristics within surfactants make the components of surfactants not easily dissolvable in water (Heinze‚ 2007). Surfactants

The catalysts currently used in PEM fuel cells are Pt nanoparticles supported on carbon black. Pt as a precious metal is expensive‚ and there have been tremendous efforts made to reduce its usage. One way is to make Pt nanoparticles as small as possible to maximize the catalyst dispersion and thus its utilization. Smaller nano particles provide larger specific surface areas for electro catalytic
