Our research focuses on trapping and controlled manipulation of sub-micron sized particles. The work included modeling, fabrication and testing of chips that employ optical forces and/or dielectrophoretic forces to trap and transport nanoparticles. Our goal is to develop lab-on-a-chip systems for biomedical and chemical applications.

Our projects include:

  • Plasmonic trapping and manipulation of nanoparticles, Stanford University (9/1/2014 - Present)
    Design, fabrication and testing of C-shaped plasmonic structures for trapping and manipulation of dielectric and metallic nanoparticles.
  • Dielectrophoretic trapping, Stanford University (August 1, 2015 - Present)
    Selective trapping and manipulation of dielectric particles using dielectrophoresis
  • Adjoint optimization, Stanford University (March 1, 2016 - December 1, 2016)
    Application of discrete and continuous adjoint optimization techniques in practical engineering problems
  • Microfluidic system design for droplet generation, Stanford University (June 1, 2017 - Present)
    We are developing a microfluidic system that can generate droplets with diameters of a few micron.
  • On chip system for small volume biochemistry, Stanford University (June 1, 2017 - Present)
    A lab-on-a-chip microfluidic system capable of trapping and manipulating particles will be developed to perform small scale chemical reactions for bio applications.
