Microchannel Capillary Electrophoresis

In this section we describe initial efforts to miniaturize conventional capillary electrophoresis experiments. Microfluidic devices were fabricated that replicated the essential qualities of capillary systems. These early microflu-idic chips incorporated electrokinetic sample handling protocols to facilitate easy sample manipulation within the microfluidic environment. Additional improvements over conventional capillary systems were realized through decreased detection limits and decreased...

Microparticles for Labonachip Applications

As previously discussed, DEP-based LOACs provide a flexible platform to displace microparticles, possibly loaded by suitable compounds, and use them as vectors to deliver precise amounts of these compounds to the relevant targets. Even though the current literature contains a few examples of micropar-ticle applications on LOACs, a comprehensive analysis of the relationship between size, chemical composition, polarity, viscosity and funtionaliza-tion of microparticles is not yet available. This...
