Sensitive Detection of Small Particles in Fluids Using Optical Fiber Tip with Dielectrophoresis

Sensitive Detection of Small Particles in Fluids Using Optical Fiber Tip with Dielectrophoresis

This work presents using a tapered fiber tip coated with thin metallic film to detect small particles in water with high sensitivity. When an AC voltage applied to the Ti/Al coated fiber tip and indium tin oxide (ITO) substrate, a gradient electric field at the fiber tip induced attractive/repulsive...
