Radiation-Induced Graft Polymerization of Vinyl Monomers with Anion Groups onto MWNT Supports and Their Application as Electrogenerated Chemiluminescence (ECL) Biosensors

Vinyl polymer-grafted multiwalled carbon nanotube (MWNT) supports with anion groups were prepared for use as biosensor supports by radiation-induced graft polymerization (RIGP) of the vinyl monomers acryloyl diphosphoric acid (ADPA), acrylic acid (AA), sodium styrenesulfonate (NaSS), and methacrylic...
