Abstract

We report a system for optical trapping, manipulation and imaging of live cells in close to real-time with a wide field of view. A fs-pulsed Ti:Sapphire source was used to trap cells whilst an Ar⁺ laser was used for confocal imaging. A single 10x/0.4NA lens and a dual scanning system enabled independent trapping, imaging and movement of cells over a field of view >1mm². We will present movies of controlled T cell and dendritic cell movement and interaction. This enables the functional study of cell-signalling processes that are fundamental to understanding the behaviour of the immune system and beyond.
