The 2018 Nobel Prize went in part to Arthur Ashkin for optical tweezers and their applications to biological systems. Optical tweezers represent a tool made of light where we use transfer of momentum of light to trap and manipulate in three dimensions small objects. We can use transfer of linear momentum of light but we also can use a transfer of angular momentum of light. For trapping to occur we need highly focused laser beam. The laser micromanipulation of a large variety of samples can be readily achieved.
From early on Ashkin demonstrated the use of optical tweezers for studies of complex biological systems and these applications are still developing. The transfer of angular momentum of light in optical tweezers led to construction of all optically driven micromachines and their use in microfluidics and other applications. It has been also possible to apply optical tweezers to studies in vivo. Join the OSA Optical Trapping and Manipulation in Molecular and Cellular Biology Technical Group for a webinar with Dr. Halina Rubinsztein-Dunlop exploring these tools made of light for which we are still finding new and exciting applications.
