Silver-enhanced nanoparticle-labeled immunoassays provide a simple, low-cost, and effective way of detecting antigens in dilute solutions. The physical mechanisms behind their operation, however, have not been fully investigated. We present a semiquantitative approach for optimizing sandwich nanoparticle immunoassays using an adsorption-controlled kinetic model. Primary antibodies were immobili...

Silver nanoparticles are extensively used in antibacterial applications. However, the mechanisms of their antibacterial action are not yet fully explored. We studied the solubility-driven toxicity of 100 × 6100 nm (mean primary diameter × length) silver nanowires (NWs) to recombinant bioluminescent Escherichia coli as a target representative of enteric pathogens. The bacteria were exposed to si...

One technique used to prepare nanoparticles material is Pulsed Laser Ablation in Liquid (PLAL), Silver Oxide (AgO) were prepared by using this technique, where silver target was submerged ultra-pure water (UPW) at room temperature after that Nd:Yag laser which characteristics 1064 nm wavelength, Q-switched, and 6ns pulse duration irradiated target. This preparation method study the effects of i...

silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. a simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  the present study aimed at the comparative study of silver nanopartic...

tumor growth is characterized by uncontrolled cell division. for centuries, silver kushta powder, composed of nano and submicro silver particles, has been used in traditional iranian and pakistani medicine for the treatment of melanoma and breast cancer. we have found that these nanocomposite particles are similar to silver nanoparticles (agnps) in size and shape and that there are so differenc...

Anisotropic nanoparticles (i.e., silver nanocubes, gold nanorods) based SERS molecular probe were designed and fabricated for the rapid and specific detection of bacterial targets in a test-in-a-tube platform utilizing a novel dual-recognition mechanism. The probes were synthesized by covalently attaching Raman tags and bacteria-specific antibodies to the surface of silver nanocubes. Specific b...

archaeological researches indicate that the use of silver was common in various practices; there were numerous mints for silver coinage across sassanid persia (circa 620 ad) indicating that persians were familiar with silver mining and its refining process. medical practice also benefited from that expertise, and in the course of the following centuries new forms of utilizing silver began to em...

conclusions: the results showed that silver nanoparticles have an antimicrobial effect against intramacrophage b. abortus 544. results: the well diffusion agar study showed that silver nanoparticles have an antimicrobial effect on b. abortus 544. the mic and mbc of silver nanoparticles against b. abortus 544 were; 6 ppm and 8 ppm, respectively. the silver nanoparticles showed antibacterial effe...

Although copper-silver ionization (CSI) has been used for 30 years to inactivate Legionella bacteria and other opportunistic pathogens in water, the literature is a mix of both successes failures. This paper reviews technology case studies help improve success CSI installations. Important properly designed system capable consistent delivery copper/silver ions at their target levels. However, ev...

Molecular docking is an important tool in drug research. Thanks to these calculations, the type and magnitude of interactions molecules with target are evaluated. It also possible perform more detailed analyzes than known experimental methods easy economical way by using results obtained current scientific developments examine different depending on bioactivity type. Cancer researches show that...
