Leading chemists and engineers concisely explain the principles behind microchip capillary electrophoresis and demonstrate its use in a variety of biochemical applications, ranging from the analysis of DNA, proteins, and peptides to single cell analysis and measuring the impact of surface modification on flow in microfluidic channels. Since surface chemistry must be carefully considered for optimal operation at this scale, the authors also discuss methods of both adsorbed and covalent surface modification for its control. Fabrication methods for producing microchips with glass, poly(dimethylsiloxane), and other polymers are also provided so that even novices can produce simple devices for standard separations. Microchip Capillary Electrophoresis: Methods and Protocols provides a practical starting point for either initiating research in the field of microchip capillary electrophoresis or understanding the full range of what can be done with existing systems.
