Optoelectronic tweezers

چکیده
Optoelectronic tweezers is a new technique to trap and manipulate particles with sizes ranging from tens of nanometers to hundreds of micrometers. Using optically-controlled dielectrophoretic force on a photoconductive electrode, optoelectronic tweezers enables complex, dynamic manipulation functions using light intensities up to 100,000 times lower than that of conventional laser tweezers. © 2007 Microoptics Group (OSJ/JSAP)

Optoelectronic Tweezers for Cell and Nanoparticle Manipulation
Optoelectronic tweezers (OET) is a new tool for noninvasive, parallel manipulation of cells and/or micro/nanoparticles. Based on light-induced dielectrophoresis, OET can trap and sort colloidal particles, biological cells, nanowires and nanoparticles using a digital light projector. In this paper, we will present the principle and recent experimental results of OET. Keywords-Optoelectronic twee...
متن کاملDynamic manipulation and patterning of microparticles and cells by using TiOPc-based optoelectronic dielectrophoresis.
We develop light-driven optoelectronic tweezers based on the organic photoconductive material titanium oxide phthalocyanine. These tweezers function based on negative dielectrophoresis (nDEP). The dynamic manipulation of a single microparticle and cell patterning are demonstrated by using this light-driven optoelectronic DEP chip. The adaptive light patterns that drive the optoelectronic DEP on...

متن کاملA noninvasive, motility independent, sperm sorting method and technology to identify and retrieve individual viable nonmotile sperm for intracytoplasmic sperm injection.
PURPOSE For intracytoplasmic sperm injection in the absence of sperm motility it can be virtually impossible to distinguish viable from nonviable sperm. A reliable means to identify viable nonmotile sperm is needed and would likely improve the intracytoplasmic sperm injection success rate. Optoelectronic tweezers are a new technology that uses light induced dielectrophoresis fields to distingui...
متن کاملOptofluidics and Optoelectronic Tweezers
Optofluidics is the process of integrating the capabilities of optical and fluidic systems to achieve novel functionalities that can benefit from both. Among the novel capabilities that an optical system can bring to the table is the ability to manipulate objects of interest in a liquid media. In the case of biological samples, the objects of interest consist mainly of cells and viruses, wherea...
