Optoelectrofluidic Manipulation & Detection Optoelectrofluidic technology allows programmable manipulation of particles or fluids in microenvironments based on optically induced electrokinetics resulted from photochemical, photoconductive, and photothermal effects [Lab Chip 2011, 11, 2518]. Based on the electrokinetic motion of particles or fluid under an electric field induced by light, an image-based manipulation of several biological materials, including blood cells [Electrophoresis 2008, 29, 1203], oocytes [Biomicrofluidics 2009, 3, 014103], swimming bacteria [Appl. Phys. Lett. 2008, 93, 143901], as well as separation and assembly of colloidal particles [Langmuir 2009, 25, 6010] has been demonstrated. Recently, our group demonstrated a rapid and selective concentration of microparticles by combining several electrokinetic mechanisms, including ac electroosmosis and dielectrophoresis, and electrostatic interactions [Lab Chip 2009, 9, 199]. The particle movements resulted from the frequency-dependent behavior according to the particle diameter. The dynamic control of local molecular concentration was also achieved by using several frequency-dependent optoelectrofluidic phenomena [Anal. Chem. 2009, 81, 5865]. This new platform could be applied to develop an integrated system for optoelectrofluidic manipulation of micro- and nanoparticles including living cells and biomolecules [Adv. OptoElectronics 2011, 2011, Article ID 482483]. Recently we report a new kind of optoelectrofluidic sandwich immunoassay scheme based on the optoelectrofluidic device coupled with conventional surface-enhanced Raman scattering (SERS) setup [Anal. Chem. 2010, 82, 7603]. This image-driven immunoassay platform as well as optoelectrofluidic SERS spectroscopy [Lab Chip 2011, 11, 2518] opens a new way for simple, fast, automated, and highly sensitive detection of antigens without any washing steps.

This paper from researchers at KAIST presents a microarray-integrated optoelectrofluidic immunoassay system to overcome a diffusion limitation problem of conventional methods under static environments that cause low reaction efficiency. Optically-induced AC electroosmotic flows actively enhanced the mass transport of molecules at the multiple assay spots of the microarray simultaneously, which reduced reaction times. |
