Super particle aims to help stop heart attacks and strokes

By age 20, many adults will have at least some build-up of plaque in their arteries; a condition known as atherosclerosis. Many of us won't even be aware of it. Regardless of whether an atherosclerotic plaque is large or ...

Better vaccines are in our blood

Red blood cells do more than shuttle oxygen from our lungs to our organs: they also help the body fight off infections by capturing pathogens on their surfaces, neutralizing them, and presenting them to immune cells in the ...

Nanoparticle

In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: In terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers. Similarly to ultrafine particles, nanoparticles are sized between 1 and 100 nanometers, though the size limitation can be restricted to two dimensions. Nanoparticles may or may not exhibit size-related properties that differ significantly from those observed in fine particles or bulk materials .

Nanoclusters have at least one dimension between 1 and 10 nanometers and a narrow size distribution. Nanopowders are agglomerates of ultrafine particles, nanoparticles, or nanoclusters. Nanometer sized single crystals, or single-domain ultrafine particles, are often referred to as nanocrystals. Nanoparticle research is currently an area of intense scientific research, due to a wide variety of potential applications in biomedical, optical, and electronic fields. The National Nanotechnology Initiative has led to generous public funding for nanoparticle research in the United States.
