Nanoparticles are engineered particles of between one and 100 nanometers in diameter, a size known as the nanoscale. To put this into context, a nanometer (nm) is one billionth of a meter, and the distance between individual atoms in a solid is between 0.1 nm and 0.4 nm. Nanoparticles the...
Gold and silver are relatively inert in bulk amounts. On the nanoscale, however, they demonstrate unique catalytic properties. For example, silver nanoparticles are an effective antibiotic. Nanoparticles of gold have proven to be efficient at removing volatile organic compounds from the atmosphere, eve...
Nanoparticles are materials that are confined to the nanoscale in all three dimensions. Engineered nanoparticles play an important role in nanotechnology. The specific properties of nanoparticles is defined by particle size, chemical composition, crystal
If you’ve read this blog before, you are likely to know what nanoparticles are: bits of matter on the 1-100 nm scale that have unique properties different from bigger sizes of the same material. But you might not know what we mean when we say “proteomics,” which sounds to me sort ...
CVD uses gaseous reactants to fabricate nanostructures on a substrate. While CVD is rapid and scalable, it requires special equipment, and the gaseous by-products are highly toxic.1Thus, industries commonly use pyrolysis for the large-scale production of nanoparticles as it is simple, efficient,...
Although "traditional" solid, uniform nanoparticles are still the most frequently reported structures, new generations of nanoparticles have been constantly emerging over the last several decades. The outcome of this nano-art extends beyond nanomaterials with alternative compositions and/or morphologies. ...
In one study from 2000, post-mortems on 29 patients with knee or hip replacement implants found mostly low levels of polyethylene nanoparticles in lymph nodes or organs. To shed light on the health impacts of microplastics more conclusively, scientists aim to do...
They also noticed that materials possess different properties of magnetism and temperature at the nanoscale [source: U.S. Department of Energy]. Because the science deals with the basic building blocks of matter, there are countless applications. Some seem almost mundane -- nanoparticles of zinc ...
Nanotechnology-on-a-chip is one more dimension of lab-on-a-chip technology. Biological tests measuring the presence or activity of selected substances bee quicker, more sensitive and more flexible when certain nanoscale particles are put to work as tags or labels. Magic nanoparticles, ...
Nanoparticles are an increasing concern because of their potential health risks. Researchers have identified a mechanism through which nanoparticles can damage the lungs, and demonstrated a method for blocking this. However, there are some potential issues that need to be considered before making this ...
