Description 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 The maleimide-functionalized silica beads were used to immobilize the bovine serum albumin (BSA)-boronic acid (BA) conjugates. Packaging 10, 25 g in poly bottle 2 g in glass bottle
