Angela M. Belcher is a materials scientist
Materials science
Materials science is an interdisciplinary field applying the properties of matter to various areas of science and engineering. This scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It incorporates...

After studying abalone shells, she worked with several colleagues at MIT and engineered a virus, known as the M13 bacteriophage whose target is usually Escherichia coli
Escherichia coli
Escherichia coli is a Gram-negative, rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms . Most E. coli strains are harmless, but some serotypes can cause serious food poisoning in humans, and are occasionally responsible for product recalls...

. M13 can be made to latch onto and coat itself with inorganic materials including gold and cobalt oxide. The long tubular virus (coated in cobalt oxide) now acts as a minuscule length of wire called a nanowire
Nanowire
A nanowire is a nanostructure, with the diameter of the order of a nanometer . Alternatively, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. At these scales, quantum mechanical effects are important —...

. Belcher's group coaxed many of these nanowires together and found that they resemble the basic components of a potentially very powerful and compact battery. In 2002 she founded Cambrios with Evelyn L. Hu of Harvard University

. Their vision relied upon the use of nanostructured inorganic materials, fabricated and shaped by biological molecules to create novel materials and processes for a variety of industries.

In 2009 Belcher and her team demonstrated the feasibility of using genetically-modified viruses to build both anode and cathode of a lithium-ion battery. These new batteries have the same energy capacity and power as cutting-edge rechargeable batteries earmarked for use in hybrid cars, as well as powering a range of electronic devices. The batteries could be manufactured using a cheap and environmentally friendly process, as the synthesis can be done near room temperature, using no harmful solvents or toxic materials.
