Nanoparticle News and Research

RSS

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.

Scientists develop laser activated carbon nanoparticles for drug, gene delivery

Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells.Carbon nanoparticles activated by bursts of laser light trigger the tiny blasts, which open holes in cell membranes just long enough to admit therapeutic agents contained in the surrounding fluid. By adjusting laser exposure, the researchers administered a small-molecule marker compound to 90 percent of targeted cells - while keeping more than 90 percent of the cells alive.

Attaching transferrin to nanoparticle surface can kill cancer cells

A normally benign protein found in the human body appears to be able - when paired with nanoparticles - to zero in on and kill certain cancer cells, without having to also load those particles with chemotherapy drugs.The finding could lead to a new strategy for targeted cancer therapies, according to the University of North Carolina at Chapel Hill scientists who made the discovery.

Scientists report potential toxicity of nanoparticles in consumer 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.
