Mutagenic effects of gold nanoparticles induce aberrant phenotypes in Drosophila melanogaster

Abstract

The peculiar physical/chemical characteristics of engineered nanomaterials have led to a rapid increase of nanotechnology-based applications in many fields. However, before exploiting their huge and wide potential, it is necessary to assess their effects upon interaction with living systems. In this context, the screening of nanomaterials to evaluate their possible toxicity and understand the underlying mechanisms currently…

In vivo assessment of CdSe/ZnS quantum dots: coating dependent bioaccumulation and genotoxicity

Semiconductor nanocrystals, or Quantum Dots (QDs), have gained considerable attention due to their unique size-dependent optical and electronic properties that make them attractive for a wide range of applications, including biology and nanomedicine. Their widespread use, however, poses urgent questions about their potential toxicity, especially because of their heavy metal composition that could cause harmful effects to human health and environment. In this work, we evaluated in vivo the…

Concentration-Dependent, Size-Independent Toxicity of Citrate Capped AuNPs in Drosophila melanogaster

Abstract

The expected potential benefits promised by nanotechnology in various fields have led to a rapid increase of the presence of engineered nanomaterials in a high number of commercial goods. This is generating increasing questions about possible risks for human health and environment, due to the lack of an in-depth assessment of the physical/chemical factors responsible for their toxic effects. In this work, we evaluated the toxicity of monodisperse citrate-capped gold…

Will graphene be a good basis for 3D printing?

In past years we've seen graphene being used for many applications: transparent and flexible touch displays, sensors, batteries, solar panels, water purifications systems and more.



Today American Graphite Technologies (AGT) announced that it is going to research the possibility of using graphene-based materials as the workking materials for 3D printing. AGT will collaborate on this with Ukraine's Kharkiv Institute of Physics and Technology ("KIPT"):…

Application and development of STED microscopy to reveal the nanoscale organization of biological membranes

Biological membranes are a complex self-organizing composite of lipids, proteins and sugars. Although membrane organization has been intensively studied, the dynamic interactions of lipids and proteins in the living system are poorly understood. The main reason is the lack of appropriate techniques to study the relevant processes with sufficient spatial and temporal resolution. One cutting-edge technical progress is the combination of superresolution STED microscopy and fluorescence…

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
