Cells of all organisms process numerous signals originating from the internal biological processes or from the environment to produce the appropriate cellular response. Designed gene regulatory ...

Synthetic biology researchers have demonstrated a new method for digital information processing in living cells, analogous to the logic gates used in electric circuits. The circuits are the largest ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

The HEF4001B is an integrated circuit having four 2-input NOR gate. The outputs of HEF4001B are fully buffered for the highest noise immunity and pattern insensitivity to the output impedance. The ...
