Holographic Optical Tweezers: Techniques and Biomedical Applications

open access: yesApplied Sciences, 2022
Holographic optical tweezers (HOT) is a programmable technique used for manipulation of microsized samples. In combination with computer-generation holography (CGH), a spatial light modulator reshapes the light distribution within the focal area of the ...

Holographic Optical Tweezers That Use an Improved Gerchberg–Saxton Algorithm [PDF]

open access: yesMicromachines, 2023
It is very important for holographic optical tweezers (OTs) to develop high-quality phase holograms through calculation by using some computer algorithms, and one of the most commonly used algorithms is the Gerchberg–Saxton (GS) algorithm. An improved GS

Nanoscopy of bacterial cells immobilized by holographic optical tweezers [PDF]

open access: yesNature Communications, 2016
Nanoscopy of non-adherent cells is currently not possible, due to their movement in solution. Here the authors immobilize and manipulate fixedE. coli by multiple optical traps; their holographic optical tweezers enable dSTORM imaging of orthogonal planes
