Rotating Live Mammalian Cells Free in Media Using Spatial Light Modulator (SLM)-Generated Optical Tweezers

Optoelectronic Tweezers – Optical Manipulation using LEDs and Spatial Light Modulators

1. Introduction Optical manipulation of biological cells in microfluidic devices is a powerful technique for high-throughput cell-based assays. It offers several advantages compared with other techniques: it is non-invasive, contamination free , and needs no or minimum fabrication for the mi-crofluidic devices. The most well-known optical manipulation tool is optical tweezers [1, 2]. To achieve...

Demonstration of polarization-insensitive spatial light modulation using a single polarization-sensitive spatial light modulator

We present a simple configuration incorporating a single polarization-sensitive phase-only liquid crystal spatial light modulator (LC-SLM) to facilitate polarization-insensitive spatial light modulation. The polarization-insensitive configuration is formed by a polarization beam splitter (PBS), a polarization-sensitive phase-only LC-SLM, a half-wave plate (HWP), and a mirror in a loop structure...

Optical tweezers: a light touch.

Optical tweezers use focused laser light to manipulate microscopic particles. We discuss the underlying physics of the technique in terms of a gradient force exerted by the light on the particles. The versatility of optical tweezers is highlighted, in particular, we explain how spatial light modulators and various imaging methods have greatly enhanced their range of applications.
