Described herein is an immobilization-free, electrochemical method of detecting a target DNA sequence in a sample. The method includes: incubating the sample with a detection mixture, applying an electric field including an alternating current electric field and a direct current offset to the detection mixture to concentrate nucleic acids in the sample and the nucleic acid probe on a positively charged working electrode, wherein a Class 2 Cas protein trans-cleaved electroactive probe is released from the nucleic acid probe when the target DNA is present in the sample and diffuses toward a negatively charged electrode; and measuring the current as potential is applied, wherein detection of a current in the detection mixture indicates the presence of the target DNA sequence in the sample.

Information is stored in existing DNA through an iterative process of creating a break in dsDNA and adding new DNA by repairing the break with a homologous repair template. The order and sequence of DNA sequences added to the breaks in the dsDNA can encode binary data. By using a context-dependent encoding scheme, three unique homologous repair templates can encode an unbounded number of bits. When the existing DNA is in a cell, the changes are heritably passed to subsequent generations of the cell. Synthesis of the homologous repair templates may be under the control of a promoter and operator. Intra- or extra-cellular signals may regulate the synthesis of homologous repair templates.
