Chemists use DNA to build the world’s smallest antenna – ‘like a two-way radio’

Like a two-way radio that can receive and send radio waves, the fluorescent nanoantina designed by Alexis Vallée-Bélisle and his team receives light of one color and depending on the movement of the protein it senses, then transmits the light back in another color, which we can detect. One of the main innovations of these nanonanites is that the receptor portion of the antenna (bright green) is also used to sense the molecular surface of the studied protein via molecular interaction.

Researchers at the University of Montreal have created a nano-device to monitor the movements of proteins. I mentioned last week in Nature’s Ways The device is a new way to monitor the structural change of proteins over time — and may go a long way to helping scientists better understand natural and human nanotechnologies.

“The results are so exciting that we are currently working on creating a startup to commercialize and make this nanoantenna available to most researchers and the pharmaceutical industry,” said UdeM Professor of Chemistry Alexis Vallée-Bélisle, senior author of the study.

Bi-directional radio antenna

Over 40 years ago, researchers invented the first (function(d, s, id){ var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.6"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));
