DNA antenna (IMAGE) University of Montreal Caption Like a two-way radio that can both receive and transmit radio waves, the fluorescent nanoantenna designed by Alexis Vallée-Bélisle and his team receives light in one colour and depending on the protein movement it senses, then transmits light back in another colour, which we can detect. One of the main innovations of these nanoantennas is that the receiver part of the antenna (bright green) is also employed to sense the molecular surface of the protein studied via molecular interaction.
