Article Synopsis
- The study explores the use of direct current insulator-based electrokinetic (DC-iEK) microfluidic devices powered by 9 V alkaline batteries to trap 2-µm fluorescent polystyrene particles.
- Particle trapping efficiency improved significantly with a higher voltage (18 V) compared to using a single battery, which only resulted in sporadic trapping.
- The findings suggest that lower voltages in DC-iEK systems are better suited for precise particle characterization rather than high-performance applications like separation or filtering.
Insulator-based electrokinetically driven microfluidic devices stimulated with direct current (DC) voltages are an attractive solution for particle separation, concentration, or isolation. However, to design successful particle manipulation protocols, it is mandatory to know the mobilities of electroosmosis, and linear and nonlinear electrophoresis of the microchannel/liquid/particle system. Several techniques exist to characterize the mobilities of electroosmosis and linear electrophoresis.
