NASA Applies for Bio-nanobattery Patent
A group of researchers at NASA has been working on a protein called ferritin, which has the unique ability to carry either a positive or negative charge. The protein is also capable of self assembling into a uniform nanolayer form. NASA sees potential in the material, suggesting that it is relatively easy to create a layer of ferritin and then cover it with another layer of the opposite charge. The outcome is a capacitor just a few nm thick, which NASA believes is stable, robust, and can be produced easily and quickly. In fact, NASA has already applied for a patent for the device.
