General description

Maleimide (2,5-Pyrroledione) is a new nanoparticle surface functional group which favors easy conjugation with cell penetration peptides. The conjugation is enabled via click chemistry to preserve its biofunctions.

Application

Rhodium-catalyzed conjugate arylation with arylboronic acids.
The maleimide-functionalized silica beads were used to immobilize the bovine serum albumin (BSA)-boronic acid (BA) conjugates.
