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.

Nanotechnology-based vaccine cures mice with type 1 diabetes

Using a sophisticated nanotechnology-based "vaccine," researchers were able to successfully cure mice with type 1 diabetes and slow the onset of the disease in mice at risk for the disease. The study, co-funded by the Juvenile Diabetes Research Foundation, provides new and important insights into understanding how to stop the immune attack that causes type 1 diabetes, and could even have implications for other autoimmune diseases.

Potential toxicity of zinc nanoparticles in sunscreen products

Scientists are reporting that particle size affects the toxicity of zinc oxide, a material widely used in sunscreens. Particles smaller than 100 nanometers are slightly more toxic to colon cells than conventional zinc oxide. Solid zinc oxide was more toxic than equivalent amounts of soluble zinc, and direct particle to cell contact was required to cause cell death. Their study is in ACS' Chemical Research in Toxicology, a monthly journal.

Nanoparticle-core polymer holds promise as weight-bearing replacement for traditional graft materials

Orthopedic surgeons are often hamstrung by less-than-ideal grafting material when performing surgeries for complex bone injuries resulting from trauma, aging or cancer. Conventional synthetic bone grafts are typically made of stiff polymers or brittle ceramics, and cannot readily conform to the complex and irregular shapes that often result from injury; in addition, they often require metallic fixation devices that require open surgeries to insert and remove.
