Nanoparticles and Human Cells

Scientists at Brookhaven National Laboratory in New York have developed a screening method to examine how newly made nanoparticles interact with human cells following exposure for various times and doses. This study throws light on how human cells interact with carbon nanoparticles. These experiments will give insight into the design of nanoparticles keeping in mind safety concerns and optimizing their use in health related applications. It may also lead to effect screen practices for carbon-based materials.

Nanoparticles is studied in nanotechnology. It is manipulation of atoms, molecules, andmaterials to form structures on the scale of nanometres (billionths of a metre).

These nanostructures typically exhibit new properties or behaviours due to quantum mechanics. In 1959 Richard Feynman first pointed out some potential quantum benefits of miniaturization. A major advancement was the invention of molecular-beam epitaxy by Alfred Cho and John Arthur at Bell Laboratories in 1968 and its development in the 1970s, which enabled the controlled deposition of single atomic layers. Scientists have made some progress at building devices, including computer components, at nanoscales. Faster progress has occurred in the incorporation of nanomaterials in other products, such as stain-resistant coatings for clothes and invisible sunscreens.
