By using a wide range of naturally abundant bio-organic raw materials, the company have avoided the environmental problems caused by other nanodot technologies that are heavy metal-based, making them toxic.

“We have created magnetic nanodots that store one bit of information on each nanodot, allowing us to store over one billion pages of information in a chip that is one square inch,” says Dr. Jay Narayan, the John C. Fan Distinguished Chair Professor of Materials Science and Engineering at NC State and author of the research.
