Dynamic DMD-Driven Optoelectronic Tweezers for Microscopic Particle Manipulation
نویسندگان
چکیده
We demonstrate dynamic manipulation of microscopic particles using a DMDproduced projection image in an optoelectronics tweezers system. Single-particle trapping and movement (up to 40 μm/sec) via optically-induced dielectrophoresis were observed. 2003 Optical Society of America OCIS codes: (170.4520) Optical confinement and manipulation, (230.0250) Optoelectronics

Dynamic 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 کاملLipid bilayer-integrated optoelectronic tweezers for nanoparticle manipulations.
Remotely manipulating a large number of microscopic objects is important to soft-condensed matter physics, biophysics, and nanotechnology. Optical tweezers and optoelectronic tweezers have been widely used for this purpose but face critical challenges when applied to nanoscale objects, including severe photoinduced damages, undesired ionic convections, or irreversible particle immobilization on...
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...
متن کاملAn optoelectronic tweezers system for single cell manipulation and fluorescence imaging of live immune cells
A compact optoelectronic tweezers system for combined cell manipulation and analysis is presented. CMOS-controlled gallium nitride micro-LED arrays are used to provide simultaneous spatio-temporal control of dielectrophoresis traps within an optoelectronic tweezers device and fluorescence imaging of contrasting dye labelled cells. This capability provides direct identification, selection and co...
متن کاملOptoelectronic tweezers
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. © 2...
