Nanoparticles: Pioneers of progress or harbingers of danger?

 Technologies based on nanoscale materials – for example, particles that are more than 10,000 times smaller than the period at the end of this sentence – play a growing role in our world.

Carbon nanofibers strengthen airplanes and bicycle frames, silver nanoparticles make bacteria-resistant fabrics, and moisturizing nanoparticles called nanoliposomes are used in cosmetics.

Nanotechnology is also revolutionizing medicine and pushing the boundaries of human performance. If you received a COVID-19 vaccine in the United States, it contained nanoparticles.

In the future, nanotechnology may allow doctors to better treat brain diseases and disorders like cancer and dementia because nanoparticles pass easily through the blood-brain barrier....<<<Read More>>>...
