Isolation of Circulating Tumor Cells by Dielectrophoresis
Dielectrophoresis (DEP) is an electrokinetic method that allows intrinsic dielectric properties of suspended cells to be exploited for discrimination and separation. It has emerged as a promising method for isolating circulation tumor cells (CTCs) from blood. DEP-isolation of CTCs is independent of cell surface markers. Furthermore, isolated CTCs are viable and can be maintained in culture, sug...
متن کاملLabel-free Isolation and Enrichment of Cells Through Contactless Dielectrophoresis
Dielectrophoresis (DEP) is the phenomenon by which polarized particles in a non-uniform electric field undergo translational motion, and can be used to direct the motion of microparticles in a surface marker-independent manner. Traditionally, DEP devices include planar metallic electrodes patterned in the sample channel. This approach can be expensive and requires a specialized cleanroom enviro...
متن کاملDielectrophoresis (DEP) of Cells and Microparticle in PDMS Microfluidic Channels
Electromanipulation of microparticles utilizing microelectrodes has demonstrated considerable promise for the characterization, separation and handling of biological cells. Presently considerable research and development effort is directed towards the development of miniaturized fluidic systems with integrated dielectrophoresis (DEP) electrodes. The design, development and fabrication of a DEP ...
متن کاملHigh Resolution Scanning Electron Microscopy of Cells Using Dielectrophoresis
Ultrastructural analysis of cells can reveal valuable information about their morphological, physiological, and biochemical characteristics. Scanning electron microscopy (SEM) has been widely used to provide high-resolution images from the surface of biological samples. However, samples need to be dehydrated and coated with conductive materials for SEM imaging. Besides, immobilizing non-adheren...
متن کاملSelective concentration of human cancer cells using contactless dielectrophoresis.
This work is the first to demonstrate the ability of contactless dielectrophoresis (cDEP) to isolate target cell species from a heterogeneous sample of live cells. Since all cell types have a unique molecular composition, it is expected that their dielectrophoretic (DEP) properties are also unique. cDEP is a technique developed to improve upon traditional and insulator-based DEP devices by repl...
