Shape dependent physical mutilation and lethal effects of silver nanoparticles on bacteria
In this report, spherical silver nanoparticle (AgNP-sp) and rod-shaped silver nanoparticle (AgNR) were prepared by chemical reduction method and their antibacterial activity against variousExpand
Elemental profile in some common medicinal plants of India. Its correlation with traditional therapeutic usage
Several parts of plants are used in herbal and Ayurvedic medicines of India. The different elemental constituents at trace levels of these plant parts play an effective role in the medicinesExpand
Synthesis and characterization of Ag nanoparticles in silica matrix by atom beam sputtering
Silver nanoparticles (Ag NPs) embedded in silica were prepared by a novel process of atom beam sputtering (ABS). Optical and structural properties of Ag NPs were studied by using ultraviolet–visibleExpand
Industrial wastes are considered as critical factors for disturbing natural ecosystems. The East Calcutta Wetlands, a Ramsar site in West Bengal, India, receives composite industrial effluents,Expand
Antibacterial properties of synthesized Ag and Ag@SiO2 core–shell nanoparticles: a comparative study
Spherical bare silver nanoparticles (AgNPs) and silica coated silver nanoparticles (Ag@SiO 2 ) have been prepared by one step chemical reduction method. The optical, structural and morphologicalExpand
Synthesis of plasmonic nanocomposites for diverse applications.
We report the synthesis of gold and silver nanostructures embedded in different dielectric matrices by atom beam co-sputtering, a novel technique. We have synthesized gold-silicon core shellExpand
