Three Dimensional Manipulation of Cells Using Holographic Optical Tweezers

Article Preview

Abstract:

A holographic optical tweezers platform was built and a multi-plane adaptive-additive algorithm was used to generating holograms for the reconstruction of optical traps in three-dimensional (3D) spaces. Experiments of manipulating cells were conducted on such platform and complex 3D structures were built with yeast cells. The results demonstrate that holographic optical tweezers can manipulate groups of cells in three dimensions and effectively trap and separate cells in the direction of the optic axis without harming the cells. Based on those versatile functions, it is proved that holographic optical tweezers is a powerful tool for single cell analysis.
