Scientists at the Columbia University have achieved a significant breakthrough by utilizing the molecular machinery of living systems to power an integrated circuit.
This is the first functional piece of electronics powered by living organisms. Previous attempts to achieve that have only made it possible for a separate component to function like that as a part of a larger system.
The science behind the bio-powered circuit is revolutionary. Researchers figured out how to integrate a conventional solid-state complementary metal-oxide-semiconductor (CMOS) circuit with an artificial lipid bilayer membrane containing adenosine triphosphate (ATP)-powered ion pumps. Simple, right? ATP is the stuff that, in living organisms, transports energy from where it is generated to where it needs to be consumed. Here, it works the same way.
