Scientists hope that one day in the distant future, miniature, medically-savvy computers will roam our bodies, detecting early-stage diseases and treating them on the spot by releasing a suitable drug, without any outside help. To make this vision a reality, computers must be sufficiently small to fit into body cells. Moreover, they must be able to “talk” to various cellular systems. These challenges can be best addressed by creating computers based on biological molecules such as DNA or proteins. The idea is far from outrageous; after all, biological organisms are capable of receiving and processing information, and of responding accordingly, in a way that resembles a computer.

Biomedical engineering research has advanced by leaps and bounds in recent years, but the field still falls short of most other types of engineering in one key respect: engineers’ ability to model their work.
With the enormous complexity involved in even the simplest of living organisms, developed over billions of years of evolution, true models tend to fall well short of the wide array of interactions taking place within an organism, making it much more difficult to rely on computers to expedite engineering research and development.
