Abstract

At the current time, the most sensitive detection methods for biological molecules are based on fluorescent tags. This requires the use of optical sources and detectors as well as the introduction of a fluorophore that can be attached to a molecule of interest. In light of these challenges, my research goal was to create a sensitive method of detection based on electrical impedance measurements rather than optical measurements. In theory, this technique has the potential for providing a detection method that can be easily implemented on multiple parallel channels on a microfluidic chip.
