DNA-based world’s tiniest antenna looks like Lego. Here is how it will help identify new drugs for cancers and intestinal inflammation - Times Now

Depending on how the protein is changing and performing its biological function, the antenna transmits varying signals. .“Like a two-way radio that can both receive and transmit radio waves, the fluorescent nanoantenna receives light in one colour, or wavelength, and depending on the protein movement it senses, then transmits light back in another colour, which we can detect,” said one of the authors of the paper and chemist from UdeM, Alexis Valle-Belisle. .“Experimental study of protein transient states remains a major challenge because high structural-resolution techniques, including nuclear magnetic resonance and X-ray crystallography, often cannot be directly applied to study short-lived protein states,” explains the researchers in their paper that was recently published in the journal, Nature Methods
