It was not so long ago that sequencing even tiny snippets of DNA was a costly, cumbersome process that required access to a state-the-art lab. Today, we ...

In 1986, a company named Applied Biosystems began to manufacture automated DNA sequencing machines based on the Sanger method (Figure 1). These machines used fluorescent dyes to tag each ...

Antibiotics are one of the greatest triumphs in the history of medical science—but these lifesaving tools have a dark side.

Teams led by LMU chemist Philip Tinnefeld have now published two studies showing how DNA origami and fluorescent probes can be used to release molecular cargo in a targeted manner.

The human genome is made of more than 6 billion letters, and each person has a unique configuration of As, Cs, Gs, and Ts—the molecular building blocks that make up DNA. Determining the sequence ...

Since 1950, a method called Edman degradation has been used to sequence proteins by chemically chopping off and identifying one amino acid at a time. But that process uses strong acid, which can ...
