Electronic spectroscopy of biological solutions in microfluidic devices
Abstract
We report the development of a new microfluidic device which allows electronic analysis of biological solutions. The device is capable of fixed-frequency and spectroscopic measurements of solutions and cell suspensions over a broad range of frequencies: from 40 Hz to 20 GHz. Since detection and analysis are based on the inherent properties of the fluid, little sample preparation is necessary. In this talk, we show that the broad frequency range enables sensitivity to different species of interest and allowance for changes in the ``background'' electrolyte (for example, salt concentration or pH). In addition, we will discuss specific applications of our device to detection of biological processes.
