The world’s smallest antenna was made in Canada with synthetic DNA – Breaking News

According to the study, the results of which were published in the journal Nature Methods, researchers at the University of Montreal in Canada have developed an antenna that is smaller than a thousandth of a human hair that receives light in one color and sends it back in a different color Interaction with the protein.

Taking advantage of the self-organization of the building blocks of DNA, which contain all of the instructions an organism needs to develop, live and reproduce, researchers have developed DNA-based fluorescent nano-antennas that can describe the functions of proteins by using short synthetic DNA – Use strands that act like interlocking Legos.


The receptors of the 5 nanometer long antenna generate a different signal by chemically reacting with molecules on the protein surface when the target protein performs a certain biological function. The meaning of these signals is determined from the light emitted by the antenna.

Thanks to the nano-antenna they developed, the researchers reported that the enzyme alkaline phosphatase was able to demonstrate interactions with many biological molecules and drugs in real time for the first time, and that this enzyme has been linked to many types of cancer and intestinal inflammation.

The new technology developed is expected to be particularly useful in new drug inventions.
