What is dielectrophoresis?

Dielectrophoresis is a technique used in microfluidics and bioengineering to manipulate particles and cells using electric fields. It works by applying a non-uniform electric field to a suspension of charged particles in a fluid, causing them to experience a force towards regions of either high or low electric field strength.

Dielectrophoresis can be used to sort and separate particles based on their size, shape, and electrical properties. It has also been used to concentrate and position particles for further analysis or manipulation, such as in the assembly of micro-scale structures.

One advantage of dielectrophoresis is that it can be used to manipulate particles without physical contact, making it suitable for handling delicate biological samples. It is also relatively simple to perform and can be integrated with other microfluidic techniques for more complex operations.

Overall, dielectrophoresis has a wide range of applications in biological and medical research, including cell sorting, drug delivery, and tissue engineering. It continues to be a valuable tool in the field of microfluidics and bioengineering.
