Excited to share our new paper in Nature Communications in collaboration with @OBasle !
We report the first artificial metallo-photoDNAzyme enabling highly enantioselective visible-light photochemistry via a DNA-embedded iridium photocatalyst.

📢DNA templates are no longer required for efficient nucleic acid ligation.
💡We introduce Charge-Transfer Assisted Ligation (CTAL): a new templated reactivity based on π-stacking donor–acceptor interactions (DAN/NDI), not base pairing.

Merci à @CNRSchimie, @umontpellier de m’avoir offert un super environnement pour exercer 40 ans de recherche dont 36 exercées au @CNRS qui ont abouti à une carrière dont je suis fière. Un grand merci à mes étudiants, ingénieurs qui ont largement contribué à ma réussite.

Mes sincères remerciements vont à l’équipe @ChembioNAC pour avoir organisé mon pot de départ entre collègues et amis. Une nouvelle page se tourne pour moi vers des activités différentes mais le flambeau des ARN modifiés et coiffés est entre de bonnes mains pour durer et réussir🤞

We were delighted to celebrate the retirement of @DebartFrancoise, closing a remarkable chapter and opening a new one.
It was a warm and heartfelt moment, reflecting her dedication and the positive impact she has had on all of us over the years.
Thank you Françoise!

We have developed an entirely new mechanism of action for gene knockdown -> trafficking of targeted mRNAs to the lysosomal, using lysosomal trafficking oligonucleotides (LyTONs)!
