“Optical force: How can it be as a powerful tool in modern science? Optical tweezers and the applications”
ABSTRACT
As the nature of the light, optical force has been widely used as a powerful tool called optical tweezers with proven applications in physics, biology, and chemistry. In this presentation, optical trapping and manipulation by using strongly focused laser beams to perform several modern functions will be shown, such as optical shaping, nanoscale surgeries on individual cells, microfluidic flow cytometry, optical angular momentum transfer and lab-on-a-chip integration of capillary electrophoresis separation with electroosmotic-flow driven droplet generation. Potential applications with optical tweezers in electro-optics, condensed matter physics, physical medicine, biotechnology and chemical analysis will also be discussed.
