Microfluidics and Nanofluidics: Fundamental understanding of liquid flow and mass (molecules, particles and cells) transfer in microchannels and nanochannels is critical to the design and process control of various Lab-on-a-Chip, or Microfluidic devices used in biomedical diagnostics and analysis. Many transport processes in micro- and nano-channels are dominated by electrokinetic phenomena at the micro-scale and nano-scale. Dr.Li's group develops theoretical models and conducts numerical simulations for various electrokinetic phenomena and transport processes in micro-/nano-channels for on-chip microfluidic applications. Experimental studies are also carried out to investigate the characteristics of various electrokinetic microfluidic processes. The liquid flow and mass transfer are generated by applied electrical fields. Liquid flow and mass transfer (ions, particles and cells) in microchannels are visualized and measured by fluorescent visualization and m-PIV techniques. Microchannels and lab-on-a-chip devices are made by a soft-photolithography and 3D printing rapid prototyping facility in Dr. Li's lab.
