DNA Robots
November 21, 2017 | Terry Sharrer
In the 64 years that scientists have known about the structure of DNA, enormous knowledge has accumulated about how it works and what it can do under manipulation. This piece describes research at CalTech where bioengineers are developing DNA robots—i.e. single-stranded DNA that can be altered to have “feet,” “arms” and hands”—which can move amino acids to “distant” locations or assemble new peptides. Fluorescent tags show this movement. Synthesizing drugs and delivering them to precise cellular sites is what these robots might do in the future. MORE
