The Microfluidic Dielectrophoretic Jet is a novel technology that combines the principles of microfluidics and dielectrophoresis to create a unique platform for manipulating and sorting particles, cells, and biomolecules. This technology has gained significant attention in recent years due to its potential applications in various fields, including biotechnology, medicine, and environmental monitoring. The Microfluidic Dielectrophoretic Jet utilizes a combination of electrical and hydrodynamic forces to generate a high-velocity jet of fluid that can be used to manipulate particles and cells with high precision.
Principle of Operation
The Microfluidic Dielectrophoretic Jet operates on the principle of dielectrophoresis, which is the movement of particles in a non-uniform electric field. The device consists of a microfluidic channel with a pair of electrodes that generate a non-uniform electric field. When a particle or cell is introduced into the channel, it experiences a dielectrophoretic force that causes it to move towards the region of high electric field strength. The microfluidic channel is designed to create a high-velocity jet of fluid that can be used to manipulate the particles and cells with high precision. The dielectrophoretic force is proportional to the polarizability of the particle and the gradient of the electric field.
Design and Fabrication
The design and fabrication of the Microfluidic Dielectrophoretic Jet involve several key steps. The device is typically fabricated using microelectromechanical systems (MEMS) technology, which allows for the creation of complex microfluidic channels and electrodes with high precision. The microfluidic channel is designed to create a high-velocity jet of fluid, and the electrodes are designed to generate a non-uniform electric field. The device is typically fabricated using materials such as glass or silicon, which are biocompatible and can withstand the high electric fields required for dielectrophoresis.
