Dielectrophoresis for Bioparticle Manipulation
As an ideal method to manipulate biological particles, the dielectrophoresis (DEP) technique has been widely used in clinical diagnosis, disease treatment, drug development, immunoassays, cell sorting, etc. This review summarizes the research in the field of bioparticle manipulation based on DEP techniques. Firstly, the basic principle of DEP and its classical theories are introduced in brief; ...
متن کاملContactless dielectrophoresis: a new technique for cell manipulation.
Dielectrophoresis (DEP) has become a promising technique to separate and identify cells and microparticles suspended in a medium based on their size or electrical properties. Presented herein is a new technique to provide the non-uniform electric field required for DEP that does not require electrodes to contact the sample fluid. In our method, electrodes are capacitively-coupled to a fluidic c...
متن کاملManipulation Microparticle Polystyrene Microparticles as Handles
Varun Saxena Using a fixed beam with a fundamental Gaussian mode, a gradient force optical trap was used to translate a single cell using a carboxylated polystyrene bead as a handle. Currently, the force with which the optical trap can manipulate an individual cell alone is very weak. In fact, the inadequate nature of the optical trap on living cells has prevented this technique from being usef...
متن کاملManipulation and trapping of sub-micron bioparticles using dielectrophoresis.
A non-uniform alternating electric field induces motion in polarisable particles called dielectrophoresis. The effect is governed by the relative magnitudes of the dielectric properties of the medium and the particles. The technology has been used to manipulate particles for biotechnological applications, including purification, fractionation and concentration of cells and microorganisms. Howev...
متن کاملDielectrophoresis for Biomedical Sciences Applications: A Review
Dielectrophoresis (DEP) is a label-free, accurate, fast, low-cost diagnostic technique that uses the principles of polarization and the motion of bioparticles in applied electric fields. This technique has been proven to be beneficial in various fields, including environmental research, polymer research, biosensors, microfluidics, medicine and diagnostics. Biomedical science research is one of ...
