Microfluidic Mixing Using Contactless Dielectrophoresis
Equipment: Plasma Power Supply Systems - Model no. AL-50-HF-A Wideband AC Power Amplifier & Model AL-T350.4 High Frequency Transformer
User: Virginia Tech
Application and Requirement: Contactless dielectrophoresis method of rapid mixing enhancements in a microfluidic system
This study provides the first experimental evidence of enhanced mixing in a microfluidic system using contactless dielectrophoresis (cDEP). Our plasma power supply system, a combination of a wideband power amplifier model no. AL-50-HF-A and a high-frequency transformer model no. AL-T350.4 was used to meet the different AC signal ranges (0–300 V at 100–600 kHz). Tests across different flow rates and AC signal ranges revealed that rectangular chambers were more efficient than circular ones.
