Optimizing light-matter interaction on the biophotonics workstation
Bañas, A., Palima, D., Tauro, S., Glückstad, J.
Researchers overcome the limitation of range of motion in the axial direction for tweezer-based traps that needed high-intensity regions and high numerical-apertures (NA) by using a counter-propagating beam geometry of the BioPhotonics Workstation. The BioPhotonics Workstation featured real-time reconfigurable counter-propagating beam traps. Intensity patterns defining the optical traps were directly mapped into an addressable light-shaping module, minimizing computational overhead. Axial manipulation was achieved by balancing the intensity ratios of the counter-propagating beams. The axial degree of freedom enabled the flipping of planar microstructures and lifting puzzle pieces of reconfigurable microenvironments. The use of low NA objectives also allowed a wide range of axial manipulation and more freedom on the sample containers.

Managing Hierarchical Supramolecular Organization with Holographic Tweezers
M. Woerdemann, A. Devaux, L. De Cola, and C. Denz
The use of light for controlling objects led to the development of optical tweezers. Now, the applications have expanded into the creation of three-dimensional structures and the control of surface structures.

Forty Years of Optical Manipulation
David McGloin and J.P. Reid
This year, as the laser celebrates its 50th anniversary, a field that was made possible through laser technology reaches an important milestone as well. Over the past 40 years, optical manipulation research has deepened our understanding of physics and biology, and it has yielded the optical-tweezer technique that is used across all the sciences.
