DNA tweezers study the interaction between a drug and its target at the molecular scale

By 30th September 2019 No Comments

The efficacy of a drug strongly depends on the time that the drug molecule spends near its target, which is usually a protein. If this interaction time is long, the drug will have a stronger effect than if the interaction time is short. Researchers at the Institut de Biologie de l’Ecole normale supérieure (IBENS) – (CNRS, INSERM, ENS Paris) led by Terence Strick and Charlie Gosse have now developed a new very-high resolution technique for observing the interaction of a single drug molecule with a single target molecule in real time. The work, reported in Nature Nanotechnology, opens up new perspectives in drug development, therapeutic antibodies and materials science.
