Optofluidic cell manipulation for a biological microbeam

Optofluidic cell manipulation for a biological microbeam.

This paper describes the fabrication and integration of light-induced dielectrophoresis for cellular manipulation in biological microbeams. An optoelectronic tweezers (OET) cellular manipulation platform was designed, fabricated, and tested at Columbia University's Radiological Research Accelerator Facility (RARAF). The platform involves a light induced dielectrophoretic surface and a microflui...

Gold nano-smolder for biological tissue manipulation

Thanks to their unique optical and electromagnetic properties, noble-metal nanoparticles are proven very useful in many scientific fields, from nanotechnology to biology, including detection of cancer cells. Irradiated gold nanoparticles, as a nano-smolder could be widely used in biomedical contexts such as tumor therapy. Laser destruction of a cancerous tissue depends on thermal and physical p...

Optofluidic Manipulation with Sub-wavelength Scale Photonics

Optofluidic transport represents the fusion of optics with microfluidics to create a new paradigm for nanoscale transport. Optofluidic transport exploits the favorable transport properties of light for the manipulation of objects in nanoscale systems. Here we demonstrate, for the first time, trapping and confinement of dielectric nanoparticles (75 and 100 nm polystyrene nanoparticle beads) usin...
