Detection and Identification of Multiple Chemicals Using a Single Input-Single Output Coupled Microresonator Array

Introduction: Mass sensors based on microresonators are typically composed of single-degree-of-freedom oscillators, with functionalized, specific or partially-specific surfaces, which utilize binding-induced resonance shifts for analyte detection [1]. Currently, to identify multiple analytes an array of microresonators is necessary. However, having a large array of isolated sensors requires an equally large number of outputs, which increases hardware and signal processing requirements
