Skip to 0 minutes and 6 secondsWelcome to the second week of this course, Nanotechnology for Health. Last week, we gave a general introduction of what nanotechnology is about and the role it plays in health care. The main focus was on its application in medical diagnosis. This week, we go more into depth in one specific application, which is the development of an electronic nose. With this nose, one can measure the gas components in your breath. The analysis of what is in your breath provides information about your health and physical condition. Dr. Ruud Steenwelle is one of the researchers at the University of Twente working on the development of this electronic nose for breath analysis. He is the main lecturer of this week.

Welcome to week 2

Last week we gave an introduction of what nanotechnology is and its role in healthcare, focusing on medical diagnosis. During this and the following two weeks we discuss in more detail the development of three different medical diagnostic tools that employ nanotechnology.

The topic of this week is the development of an electronic nose. With this nose you can measure the gas components in your breath. This can give important information about the medical condition of your lungs.

In some steps the course delves into the physics and mathematics description and analysis of the device. Don’t worry if you do not quite understand all details of these steps. They are provided for those interested in or with more background of these aspects of the technology.

Next to the technological aspects we continue this week also the discussion about the impact of new technology on society: how desirable are new or better diagnostic tests?

Our main lecturer this week is Dr. Ruud Steenwelle of the Inorganic Materials Science group at the MESA+ Institute for Nanotechnology of the University of Twente. He works on the electronic nose for detection of diseases in breath.
