Adenine 'Tails' Make Tailored Anchors for DNA

Caption: Single-strand DNA can be anchored to a gold substrate for use in biodetectors by attaching a tail of adenine bases. Adenine's strong affinity for gold not only bonds the strands in place but also allows some control over the spacing by adjusting the length of the tail.
