Several fundamental research and applications in biomedicine and micro-fluidics often require controlled manipulation of collection of suspended micro- and nanoscale particles. Speckle tweezers, by incorporating randomly distributed light fields, present an elegant approach for such tasks. They use a very low laser power and simple optics, and are capable to be operated on mixture of various types of particles.
In this talk we will introduce speckle tweezers and present some of their exciting aspects and applications.
