An ultrasensitive nanoparticle-based biomolecule detection method, known as BioBar-Coding (BBC) was recently developed by the Mirkin Group, which utilizes magnetic microparticle probes (MMP) functionalized with monoclonal antibodies that specifically bind to the target of interest [prostate-specific antigen (PSA) in this case; PSA is a prostate cancer marker and a potential breast cancer marker...

Introduction: Astaxanthin, a highly active oxidant, possesses potential effect on human health. However, with the oily characteristic, ability to disperse in an aqueous environment has limited its application. Therefore, aim of this study is fabrication stable astaxanthin emulsion water. Methods: In study, was fabricated using polysorbate (tween 60/80) or lecithin. The dispersing methods magnet...

introduction population growth and development of various industries have turned water pollution into one of the most fundamental problems in the world. researches indicate that, today, underground aquifers, especially in the large and populous cities of the world, are faced with many problems caused by infiltration of industrial wastewater, presence of absorption wells for disposal of human se...

The switching behavior of isolated nanoscale nickel and cobalt bars, which were fabricated using electron-beam lithography, was studied as a function of bar length. The bars have a 35 nm thickness, a 100 nm width, and a length varying from 200 nm to 5 mm. Magnetic force microscopy showed that except for the Ni bars with a length equal to or less than 250 nm, all other as-fabricated bars were si...

Illusory line motion (ILM) refers to a motion illusion in which a flash at one end of a bar prior to the bar's instantaneous presentation or removal results in the percept of motion. While some theories attribute the origin of ILM to attention or early perceptual mechanisms, others have proposed that ILM results from impletion mechanisms that reinterpret the static bar as one in motion. The cur...

This study evaluated the biological activity of an ether extract and barbatic acid (BAR) from Cladia aggregata on embryos and adult mollusks of Biomphalaria glabrata, cercariae of Schistosoma mansoni and the microcrustacean Artemia salina. The ether extract and BAR were obtained by successive extractions with diethyl ether. The obtained extracts were analyzed using thin-layer chromatography (TL...

Knowledge and control of mixing in batch processes can prevent yield losses during scale-up. Therefore, this study, a new heat-mixing model based ono the measurement heat distribution after an applied pulse, is proposed. The was developed to predict mesomixing support scale-up, scale-down, design optimisation reactors. proposed considers influences rotational speed, stirrer type, solvent, stirr...

Magnetohydrodynamics may potentially provide a convenient means for controlling fluid flow and stirring fluids in minute fluidic networks. The branches of such fluidic networks consist of conduits with rectangular cross sections. Each conduit has two individually controlled electrodes positioned along opposing walls and additional disk-shaped electrodes deposited in the conduit's interior away ...

Calcium oxide is one of the appropriate catalysts for biodiesel production. In this study, cheap and compatible with environment catalyst has been used. Mussel shell of Persian Gulf coast is one of the sources of calcium carbonate that is converted to calcium oxide at calcination temperature up to 950°C. Transesterification reaction was carried out at optimum condition of our previous study...
