DNA, the blueprint of life, is best known for its fundamental role as genetic material—storing and transmitting biological information through the precise sequence of its bases. For decades, this ...

Scientists developed a light-responsive artificial nucleic acid that enables reversible, controllable crosslinking within DNA, opening doors for nanomedicine, DNA nanotechnologies and drug delivery.

Using an atomic force microscope tip as a pen and different single-stranded DNA as inks, scientists at Northwestern University have demonstrated a technique that could lead to the ultimate ...
