A fundamental goal of synthetic biology is to predictably and efficiently reprogram cells to perform computations and carry out specific biological tasks 1. Cells genetically engineered with ...

As a powerful material, DNA presents great advantages in the fabrication of molecular devices and higher-order logic circuits ... inputs. Another novel feature is that the developed half adder ...

The output of the half-adder is a result of 0 or 1 and a carry of 0 or 1. Additional circuits shift the operation to the next binary digit on the left until the entire number has been added.
