« Click and Release » chemistry for the targeted delivery of drugs in vivo


​A team from the SCBM, in collaboration with the SPI, the IC2MP and the University Hospital of Poitiers, has developed a bioorthogonal chemistry strategy that allows, in vivo, the controlled release of active ingredients contained in micelles-targeting cancerous tumors. These results pave the way for new strategies for targeted drug delivery.

​Abstract of the original paper

A bioorthogonal approach is explored to release the content of nanoparticles on demand. Exploiting our recently described click‐and‐release technology, we developed a new generation of cleavable micelles able to disassemble through a sequential enzymatic and bioorthogonal activation process. Proof‐of‐concept experiments showed that this new approach could be successfully used to deliver the substances encapsulated into micelles in living cells as well as in mice by two complementary targeted strategies.
