About this course

Nanotechnology and sensors are broad, interdisciplinary areas that encompass (bio)chemistry, physics, biology, materials science, electrical engineering and more. The present course will provide a survey on some of the fundamental principles behind nanotechnology and nanomaterials and their vital role in novel sensing properties and applications. The course will discuss interesting interdisciplinary scientific and engineering knowledge at the nanoscale to understand fundamental physical differences at the sensors. By the end of the course, students will understand the fabrication, characterization, and manipulation of nanomaterials, sensors, and how they can be exploited for new applications. Also, students will apply their knowledge of nanotechnology and sensors to a topic of personal interest in this course.

Learning outcomes

Nanotechnology and sensors is a course for people who are interested in learning about novel sensing tools that makes use of nanotechnology (a technology that relies in the regime between one to hundred nanometers, viz. billionths of the meters) to screen, and monitor various events in either our personal or professional life. Together, we will discover the fascinating world of nanoland that bumps up against the basic building blocks of matter. As such, we will lay the groundwork for infinite innovative applications in every part of our daily life, starting from in-vivo and ex-vivo diagnosis and treatments of diseases, continuing with quality control of goods and environmental aspects, and ending with monitoring security issues. In this endeavor, we will learn how to fabricate such new tools, how to characterize them, how to control them, and how to integrate them in the various applications.

Examination

GRADING POLICY This course will have three types of graded activities that will be included in your overall course grade. These include: • Weekly quizzes: At the end of each class, you will be asked to complete a quiz. These quizzes will provide you with an opportunity to review what you have learned throughout the week. You may take these quizzes up to 3 times as you wish. Once answered correctly, the weekly quizzes will count for 30% of your overall course grade. • Open Assignments: Two short open written assignments will be presented during the course, and will be conducted individually. Assignment will count for (1) 10% and (2) 20% of your overall course grade. • Final project: At the end of the course you will be asked to complete a final project. The final project will be conducted in groups of 4-5 students. It will consist of a written report that focuses on the utilization of nanotechnology and sensors to imitate a specific sense that relates to human senses: vision, hearing, taste, smell, or touch. Other non-specific senses such as balance and pains can be included as well. The final project should include, but not confined to: (a) multidisciplinary presentation and discussion of the overall design approach; (b) fabrication (c) characterization (d) application of the targeted artificial sense. The report shall NOT exceed 10 pages, written in 11-12 font size, 1.5 line spacing, and 2.5 cm margins from each side of the document. This will be accounting for 40% of your overall course grade.
