Forging a new periodic table using nanostructures

February 19, 2013 – 11:00 am
  • Forging a new periodic table using nanostructures - Northwestern University's Chad Mirkin has developed a new set of building blocks based on nanoparticles and DNA. Using these tools, scientists will be able to build -- from the bottom up, just as nature does -- new and useful structures. Mirkin has built more than 200 different crystal structures with 17 different particle arrangements. Some of the lattice types can be found in nature, but many are new structures that have no naturally occurring mineral counterpart.

    Carmen Drahl of C&EN Storifies #arseniclife

    Now public - the peer review exchange for the controversial and now disproved 2010 paper that claimed a bacterium weaved arsenic into its DNA and biomolecules. USA Today reporter Dan Vergano and the papers investigative team obtained the reviewer comments from NASA through a Freedom of Information Act request. Scientists and journalists had heated discussions about what to take away from the new information, and about whether the whole saga came down to honest mistakes.

    Shall I compare thee to a strand of DNA? | Chemistry World - For billions of years DNA has been life’s data storage medium. Now, scientists have used DNA to code and store their media and information, from all of Shakespeare’s sonnets to an audio recording of Martin Luther King’s ‘I have a dream’ speech.(10.1038/nature11875)
