Towards Point-of-Use Dielectrophoretic Methods: A New Portable Multiphase Generator for Bacteria Concentration World Congress On Medical Physics And Biomedical Engineering: Radiation Oncology 41, 856-859
This manuscript presents portable and low cost electronic system for specific point-of-use dielectrophoresis applications. The system is composed of two main modules: a) a multiphase generator based on a Class E amplifier, which provides 4 sinusoidal signals (0°, 90°, 180°, 270°) at 1 MHz with variable output voltage up to 10 Vpp (Vm) and an output driving current of 1 A; and b) a dielectrophoresis-based microfluidic chip containing two interdigitated electrodes. The system has been validated by concentrating Escherichia Coli at 1 MHz while applying a continuous flow of 5 ?L/min. Device functionalities were verified under different conditions achieving a 83% trapping efficiency in the best case. © Springer International Publishing Switzerland 2014.
