To create color, different small DNA strands linked to fluorescent molecules (markers) that can emit either red, green or blue color are hybridized to a long complementary DNA strand on the surface.

DNA has been used for years to store data, but encoding information into the molecule is painstaking work. Now, researchers have drastically sped it up by mimicking a natural biological process ...

When these "probes" encounter DNA biomarkers that have a corresponding, or complementary, genetic sequence, the two strands bind, sending a signal that is picked up by the device.

For the past 20 years, researchers have been creating nanoparticles from DNA strands by modifying the connections that keep DNA in its double-helical form. This allows them to create self-assembling ...

Technology DNA nanobots can exponentially self-replicate Tiny machines made from strands of DNA can build copies of themselves, leading to exponential replication.
