An optical manipulation technique that can securely control the position, orientation and shape of non-spherical microscopic samples, such as living cells, could have direct applications in biophotonics and soft matter physics. Most experiments using optical tweezers have focused on trapping spherical particles, where the optical forces and responding motion of microspheres can be easily predicted based on physical principles. However, when this method is used for trapping objects with complicated shapes, it can induce unstable motion in the particles and provide only limited control of...Read full articleRelated content from Photonics MediaARTICLESIntravital Imaging Provides Insight into Liver Disease ProgressionThe high-resolution, 3D-viewing capabilities provided by a new microscopy method from the Korea Advanced Institute of Science and Technology (KAIST) could lead to insights into nonalcoholic fatty...BioPhotonics Nov/Dec 2020 IssueAO Two-Photon Endomicroscopy Achieves Synaptic ResolutionScientists from the Hong Kong University of Science and Technology (HKUST) developed a technology for in vivo imaging of deep brain structures at synaptic resolution.
