New Sensor Can Detect 4 Different Molecules, Massachusetts Institute of Technology (MIT) Study

Using genes as interchangeable parts, synthetic biologists design cellular circuits that can perform new functions, such as sensing environmental conditions. However, the complexity that can be achieved in such circuits has been limited by a critical bottleneck: the difficulty in assembling genetic components that don't interfere with each other. Unlike electronic circuits on a silicon chip, biological circuits inside a cell cannot be physically isolated from one another. "The cell is sort of a burrito. It has everything mixed together," says Christopher Voigt, an associate professor of biological engineering at MIT.
