An efficient approach for modular assembly of multifunctional bioconjugates from oligosaccharides, peptides and proteins with fluorescent probes/affinity tags based on MoritaâBaylisâHillman (MBH) reaction in aqueous medium has been developed.

Polymer modification is a fundamental scientific challenge, as a means of both upcycling plastics and extracting a stimulus response from them. To date, the overwhelming majority of polymer modifications has focused on the polymer periphery. Herein, we demonstrate nearly quantitative, scission-free modification of polymer backbones, namely, a metamorphosis of polyesters into vinylpolymers resembling
