Abstract

Optically induced dielectrophoresis (ODEP) provides a powerful method for parallel manipulation of micro/nano

Theoretical investigation of dielectrophoretic effect for carbon nanotubes in optoelectronic tweezers

“…By comparison with the CNT particle without the dielectric layer, the total DEP force decreases with applied frequency. This demonstrates the manipulation of the CNT particle at low frequencies in many of the OET experiments (Hsu and Lee, 2014;Lee et al, 2010;Liu et al, 2014;Zheng et al, 2013). Increasing the thickness of the shell reduces the x-and y-directional component forces because the increased volume results in the polarization effect induced by the vertical electric field along the z-axis direction.…”

“…The bias voltage V=20V peak-to-peak is applied between the top and bottom boundaries, which are of the same order of magnitude as that used in the experiments (Liu et al, 2014;Zheng et al, 2013). The research on the CNT particle that is subjected to the DEP force is described in detail below.…”

“…Afterward, they developed a novel CNT-based sensor to measure the temperature and flow velocity of bio-samples within the OET platform (Hsu and Lee, 2014). Zheng et al (2013) reported that image acquisition, image analysis, and light pattern generation modules were automatically used to assemble MWCNTs into arrays in the OET device. Moreover, a new process for fabricating polymeric electrodes based on a composite solution of conductive polyaniline particles and MWCNTs using optically induced DEP was presented by Liu's group (Liu et al, 2014).…”

Optoelectronic tweezers: a versatile toolbox for nano-/micro-manipulation

“…OET has been used to manipulate and assemble a variety of nanomaterials, including semiconductor and metallic nanowires, 84,87,122,123 carbon nanotubes, 124,125 graphene nanoplatelets, 100,126,127 conductive nanoparticles, 83,86,114,115,127,128 and metal ions. [129][130][131][132] The size of the manipulated nanoparticles ranges from a few tens of nanometers to a few hundreds of nanometers.…”

The Effect of Proteome and Lipidome on the Behavior of Membrane Bound Systems in Thermally-Assisted Acoustophoresis

“…This could be done by two cylindrical lenses. 111 which is actually based on optically induced electrophoresis (ODEP) 112 and optical chromatography (OC), which works mostly based on the resulting force of the balance between microfluidic drag force and optical radiation force. 113 separation of particles using "optical tweezers" is based on the entrapment of particles towards the center of the beam by optical gradient force.…”
