תחומי מחקר

Our lab aims at researching novel ways of creating new micro/nano-scopic structures and understanding how these structures could be further manipulated. We intended to get better understanding of the underlying scientific principles that govern these processes while developing these techniques for envisioned useful applications.   

 

  • Influencing polymerization & phase separation processes with Holographic Optical Tweezers
  • Developing bubble based acousto-driven micro-particles
  • Advancing light controlled microfluidics
  • Creating position sensitive micro structures
