Abstract: Disclosed herein are systems and methods for quantifying bacteriophage virulence, measuring phage-host dynamics and parameters, including phage-host range, phage interactions with biological samples and with immune systems, and label-free bacterial detection/diagnostics, that are amenable to automation, high-throughput, and functional in complex media. In some embodiments, a label-free interferometry system transduces the light reflected by a sensor and any molecules attached thereto to a real-time signal comprising a sensorgram from which infectivity parameters such as binding kinetics and lysis time can be derived.
