Abstract

We developed a new surface modification method using poly(methyl methacrylate) (PMMA) with a film of a cellulose derivative to ensure the long-term stability of the modification. For electrophoretic protein separation using PMMA chips as well as other polymeric chips, protein adsorption is so inevitable that analytical errors (band broadening, low detection sensitivity) are unavoidable. However, our new method overcame these drawbacks of polymeric materials and provided much better analytical performances (higher theoretical plates and consecutive runs in a single channel) than other reported methods of surface modification.
