Abstract
In an embodiment, a system includes a plurality of sensor devices contained in a plurality of wells contained in a well-plate assembly. The sensor devices are used in a plurality of oscillators. Each oscillator generates a frequency and a resistance based on a quality of living biological cells contained in a corresponding well. The quality may include, for example, surface coupled mass, density, viscosity, and/or viscoelasticity of the living biological cells. The system also includes logic for measuring a resonant frequency and motional resistance associated with each sensor device and logic for processing the measured resonant frequency and motional resistance. Moreover, the system includes logic for displaying one or more graphs showing one or more characteristics of the living biological cells contained in the wells.
