Silencing RNA nanotherapy shows promise against pancreatic cancer

Despite advances in cancer survival, more than 90 percent of people with pancreatic cancer die within five years. Most patients with pancreatic tumors (and half of those with colorectal cancers) carry a mutation in the KRAS ...

Nanoparticles wiggling through mucus may predict severe COPD

In a proof-of-concept experiment, researchers from Johns Hopkins Medicine say they have successfully used microscopic man-made particles to predict the severity of patients' chronic obstructive pulmonary disease (COPD) by ...

New sensors could lead to earlier lymphoma diagnosis

CNBP researchers have developed a new method of detecting multiple cytokines—the body's messenger proteins—in very small volume samples, which could lead to earlier diagnosis of diseases such as lymphoma.

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.
