Course Objectives

This course will provide an in-depth analysis of the origin of the extra-ordinary sensitivity, fundamental limits, and operating principles of modern nanobiosensors. The primary focus will be the physics of biomolecule detection in terms of three elementary concepts: response time, sensitivity, and selectivity. And, we will use potentiometric, amperometric, and cantilever-based mass sensors to illustrate the application of these concepts to specific sensor technologies. Students of this course will not learn how to fabricate a sensor, but will be able to decide what sensor to make, appreciate their design principles, interpret measured results, and spot emerging research trends.

Who Should Take the Course

Engineers, chemists, physicists, technology developers, and product managers who have an interest in the emerging field of nanobiosensing.

Prerequisites

Freshman/sophomore level preparation in physics, chemistry, biology, and mathematics.
