Il Nobel per la Chimica 2022 è stato assegnato agli americani Carolyn Bertozzi e Barry Sharpless e al danese Mortem Meldal per lo sviluppo di tecniche per ingegnerizzare le molecole biologiche.
I tre dividono equamente il premio per avere aperto la strada alla cosiddetta "chimica a scatto", inaugurata circa 20 anni fa da Sharpless, e che consiste nella possibilità di unire le molecole in modo più efficiente e nello stesso tempo più semplice. Una tecnica che, grazie a Bertozzi, è stata applicata anche alle molecole biologiche.
Tante le applicazioni, comprese quelle relative alla chimica verde e a terapie ad alta precisione contro i tumori.
Sharpless, 81 anni, aveva già ricevuto il Nobel nel 2001; con questa nuova attribuzione diventa quindi la quinta persona al mondo ad essere stata premiata due volte dall’ Accademia reale svedese delle scienze.
