By implementing gold and gold-silver nanowires, researchers developed flexible biosensor platforms that can also perform logical operations.

With two failures it will be wrong, but at least the result is unambiguous. Voting Logic in a Circuit Consider the circuit shown above. The output should be the vote of the three flip flops.

Logical functions. When studying logic, one must begin with the basic functions. Input values can be combined using the logical AND, OR, and exclusive OR (XOR) functions (Fig. 1 at right). Logic gates ...

The circuit must change the externaltrigger clock’s frequency to obtainthe best frame rate. The CCD sensorsthat go into the linear-image-sensormodule have 12,288 pixels, and eachpixel measures 5×5 ...

Digital logic circuits in yeast with CRISPR-dCas9 NOR gates. Nature Communications, 2017; 8: 15459 DOI: 10.1038/NCOMMS15459 ...

The circuits successfully performed the sum-of-product operation at 2.8 kHz. The full potential of memristors was demonstrated when the devices were made to actively re-program themselves.

The circuits, described in the Feb. 10 online edition of Nature Biotechnology, could be used as long-term environmental sensors, efficient controls for biomanufacturing, or to program stem cells ...
