MIT Harnesses a Virus to Make Batteries

At the Massachusetts Institute of Technology (MIT), viruses are making batteries. This seemingly farfetched practice is the work of a team of scientists who have genetically engineered viruses to produce the components of a microscopic battery, which then can be printed onto a substrate. Led by Angela M. Belcher, professor of biological engineering and materials science and engineering, the team says that the batteries can be transferred to a number of different types of surfaces. They measur...
