The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...

DNA sits in sunlight every day, absorbing ultraviolet radiation that can set off the kind of chemical changes linked to ...

The newest DNA sequencing technology from Swiss multinational Roche doesn’t measure DNA directly but in fact analyzes a different polymer altogether. The technology is not yet available for sale, but ...

Thymine modified polymer for delivering DNA into cells. A thymine modified compound, poly (ethylene glycol) (PEG), is bound to DNA through an annealing process, then delivered by intramuscular ...

Schematic showing a single DNA duplex bridging two gold electrodes (yellow) patterned on a silicon nitride substrate (green). The setup allows measurement of electrical conductance as metal ions bind ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life. A new study from King ...

There’s been this dream for decades. What if we could just print out an entire gene directly, one base at a time? —Daniel Lin-Arlow, Ansa Biotechnologies As scientists set their sights on cell and ...
