StoreDot was founded in 2011 to develop peptide-based quantum dots originally discovered at Tel Aviv University. The materials have a wide range of applications from displays, through non-volatile memory to data storage to medical applications. The company is working on battery for a cellphone that would have a rapid charge capability and is moving towards trials and is in talks with Samsung, according to a Wall Street Journal report.

Quantum dots are nanocrystals of semiconductor material where the physical dimensions allow quantum mechanics to effect electronic properties. This also means that the electronic properties are highly tunable depending on the shape and size of the nanocrystals. StoreDot’s breakthrough is the discovery of bio-organic quantum dot materials. Previous quantum dot materials have included toxic materials such as arsenic or heavy metals such as cadmium.

Earlier in 2013 StoreDot received $6 million of venture funding from strategic and private investors, which it planned to use to advance its technology for mobile electronic equipment applications.

"Having built our Nanodot core technology, the company’s initial focus will be to introduce dramatic improvements in next-generation smartphones and tablets. This funding is a crucial step enabling us to take our product development efforts to the next level, and develop products that will be available for use in 2015," said Doron Myersdorf, CEO of StoreDot, in a statement issued at the time.

The Nanodots consist of chemically synthesized organic peptide molecules that measure about 2nm in diameter. They are easily synthesized and show diverse electrochemical properties including red, green and blue luminescence. StoreDot reckons more vivid displays and batteries with better power efficiency can be created using the materials.

StoreDot batteries will be charged much faster than current batteries, and will withstand thousands of charge/discharge cycles, prolonging battery life, the company claimed. StoreDot is also working on non-volatile memory storage and camera image sensors using the nanodot materials.
