Abstract
To diagnose complex diseases and perform advanced drug screening and chemical monitoring, we need sensors capable of broadband, multi-analyte detection. This is achieved either by multiplexing affinity probes to capture different target analytes, or through mass or vibrational spectroscopy. While affinity-based techniques currently dominate and are capable of high specificity and sensitivity, probe multiplexing can be time consuming, expensive, and difficult to execute reliably outside of a laboratory environment. On the other hand, spectroscopic chemical detection is label- and affinity-free, but often requires costly and bulky instrumentation. In this thesis, we describe an affinity-free sensor for measuring vibrational signatures of analytes in liquid samples, which can be implemented on a scalable and fully-electronic platform. This relies on resonant electrochemical charge transfer at room temperature, which is made possible by nanoscale interface engineering and low-noise potentiostatic feedback. We describe advances in the knowledge and technology required to realize key aspects of this platform, including the nanoscale sensor site, electrochemical measurement system, and signal analysis framework. Together, these pave the way for continued development of a practical electronic platform for molecular fingerprinting platform in complex samples.
