Nanotechnology and nanosensors are broad, interdisciplinary areasthat encompass (bio)chemistry, physics, biology, materials science, electricalengineering and more. The present course will provide a survey on some of thefundamental principles behind nanotechnology and nanomaterials and their vitalrole in novel sensing properties and applications. The course will discuss interesting interdisciplinaryscientific and engineering knowledge at the nanoscale to understand fundamentalphysical differences at the nanosensors. By the end of the course, studentswill understand the fabrication, characterization, and manipulation ofnanomaterials, nanosensors, and how they can be exploited for new applications.Also, students will apply their knowledge of nanotechnology and nanosensors toa topic of personal interest in this course.
