This video is part of the nanoHUB-U course "Principles of Electronic Nanobiosensors". (https://nanohub.org/courses/PEN)

This course provides an in-depth analysis of the origin of the extra-ordinary sensitivity, fundamental limits, and operating principles of modern nanobiosensors. The primary focus is the physics of biomolecule detection in terms of three elementary concepts: response time, sensitivity, and selectivity. And, it potentiometric, amperometric, and cantilever-based mass sensors to illustrate the application of these concepts to specific sensor technologies.
