We demonstrate an optoelectronic tweezer (OET) integrating with a lensless, ultra wide-field imaging system for real-time interactive optical manipulation over a large field of view. This system enables, for the first time, simultaneous on-chip detection and optical manipulation of individual 10-mum microparticles, size of average mammalian cells, over an area of 6.55 times 4.92 mm2, a field of view...
We demonstrate a novel single-cell surgery tool that integrates photothermal effects of gold nanoparticles with microcapillary techniques. A transient hole opening of the cell membrane at the tip of the micropipette was accomplished using laser-induced localized heating of nanoparticles. A control experiment using a conventional glass pipette of the same size without gold nanoparticles is also performed...
According to the concept of cell physiology, when the cells contact the extracellular matrix (ECM), the cell will adhere, spread and migrates. Despite the sophistication of experimental and computational approaches in cell and molecular biology, the mechanisms by which cells sense and respond to mechanical stimuli are poorly understood. In order to evaluate the characteristics of the cellular physiology,...
Optoelectronic tweezers (OET) provide a powerful tool for the manipulation of micro- and nanoparticles. The OET device produces an optically controlled dielectrophoretic force, allowing complex dynamic manipulation patterns using light intensities up to 100 000 times lower than that of optical tweezers. Using OET, we demonstrate the separation of live and dead human B cells, and the separation of...
Optoelectronic tweezers is a new tool for parallel optical manipulation of colloids and cells. Using a digital projector to pattern dynamic virtual electrodes on a photoconductive surface, we demonstrate parallel trapping, transporting, and sorting of micro/bio-particles
