Nematode Caenorhabditis elegans has been developed in a variety of environmental studies to address adverse effects of a wide range of toxicants. In the present study, we compared the toxicities of three metal oxide nanoparticles (NPs) including TiO(2)-NPs, ZnO-NPs, and SiO(2)-NPs with the same nanosize (30 nm) after prolonged exposure from L1-larvae to adult at environmental relevant concentra...

Extensive use of nanoparticles (NPs) in consumer and industrial products has led to concerns about their potential environmental impacts; however, the influences of different NPs (e.g., nZVI (nano zero-valent iron), Ag NPs, Fe2O3 NPs and MgO NPs) on the anaerobic digestion of sludge have not yet been studied in depth. Additionally, a new guideline or the use of different NPs in the anaerobic di...

Metal nanoparticles (NPs) are of great interest due to their special optical, [ 1–3 ] electronic, [ 4–8 ] and catalytic [ 9,10 ] properties. [ 11 ] Among metal NPs, Au NPs have been investigated most extensively because of their facile preparation, resistance to oxidation, and surface plasmon resonance (SPR) band that can absorb and scatter visible light. [ 3 ] Core/ shell and alloy bimetallic ...

background: sensitive and glucantime (ma) resistance leishmania tropica are referred to those isolates, which are responsive, or non-responsive to one or two full courses of treatment by ma systematically and/or intra-lesionally, respectively. in this study, we evaluated the antileishmanial activity of biogenic selenium nanoparticles (se nps) alone and in combination with ma against sensitive a...

biofabrication by using fungi is an exciting recent interest to develop an eco-friendly production of metallic nanoparticles (nps) for pharmaceutical applications. this study aimed to synthesize and characterize gold (au) and silver (ag) nps by using penicillium simplisimum. the fungus was grown in fluid czapek dox broth on shaker at 28 ºc and 200 rpm for ten days. then the supernatant was sepa...

The quest for early detection and treatment of diseases has led to intense research on theranostics [1]. With diagnosis and therapy combined onto a single platform, theranostics enables real-time monitoring of the status of disease treatment and allows for timely adjustment of type and dose of drugs, paving the way towards personalized medicine. The unique physiochemical properties of nanoparti...
