Optical particle detection integrated in a dielectrophoretic lab-on-a-chip
نویسنده
چکیده
The design and fabrication of a dielectrophoretic ‘lab-on-a-chip’ device for bioparticle processing and counting is presented. The device consists of a multi-layer travelling wave dielectrophoretic electrode array for manipulating particles and/or fluids, microchannels for delivering samples and optical fibres for counting particles and/or measuring their velocities. Single particles were detected optically using either light scattering or fluorescence emission. The technology described in this study is potentially applicable to a range of particulate diagnostic systems. (Some figures in this article are in colour only in the electronic version)

Integrated microsystem for dielectrophoretic cell concentration and genetic detection.
We have directly integrated a continuous-flow, electrokinetic method of bacterial cell concentration with room temperature, sequence-specific genetic detection. The system we have developed traps cells from a continuous-flow sample stream via dielectrophoresis, providing a 160-fold increase in cell concentration. PDMS microvalves then define a 100 nL volume around the trapped cells to which cel...

A new biosensing system is described that is based on the aggregation of nanoparticles by a target biological molecule and dielectrophoretic impedance measurement of these aggregates. The aggregation process was verified within a microchannel via fluorescence microscopy, demonstrating that this process can be used in a real time sensor application. Positive dielectrophoresis is employed to capt...

متن کاملHybrid optofluidic integration 3
Complete integration of microfluidic and optical functions in a single lab-on-chip device is one goal of optofluidics. Here, we demonstrate the hybrid integration of a PDMS-based fluid handling layer with a silicon-based optical detection layer in a single optofluidic system. The optical layer consists of a liquid-core antiresonant reflecting optical waveguide (ARROW) chip that is capable of si...
