TL;DR: The ability of the chip to reach high upper frequency of operation is demonstrated, thus overcoming the low-frequency Debye screening limit at nearly physiological salt concentrations in the electrolyte, and allowing for detection of events occurring beyond the extent of the electrical double layer.

TL;DR: This work has developed a measurement platform for performing high-frequency AC detection at nanoelectrodes and shows here that sensitivity down to the attofarad level combined with the small electrode size permits detection of individual 28 nm diameter particles as they land on the sensor surface.

TL;DR: A simplified lumped geometrical and electrical model for the high-frequency impedance spectroscopy (HFIS) response of nanoelectrodes to capsids and full viruses is developed to test the theoretical response of a realistic HFIS CMOS biosensor platform to different viruses.

TL;DR: Bayesian estimation methods to extract physical parameters and interpret the statistical variability in the measured outputs of a dense nanocapacitor array biosensor platform are proposed.

TL;DR: LightSpeed as discussed by the authors is a low-cost real-time volumetric handheld optoacoustic imager based on a new compact software-defined ultrasound digital acquisition platform and a pulsed laser diode.
