Course description:The electrochemical detection methods form a beautiful comprehensive part of this course: starting from electrochemical processes at an electrode and the subsequent mass transport phenomena result in the three basic operational principles (potentiometry, amperometry and conductometry). When the relation between the variable to be determined (ionic species and/or its concentration) and the measured quantity (voltage, current or conductance) is known, the relevant examples follow: the oxygen electrode (Clark electrode), the carbon dioxide sensor (Severinghaus princinciple) and the pH sensors (glass electrode). Additionally, other chemical biosensors like the glucose sensor, and biosensors based on optical detection principles are treated. The treatment of physical sensor systems is guided by the biomedical application: blood pressure and flow, lung volume and capacity. A bridge to the course Lab-on-a-Chip  is formed by some examples of micro Total Analysis Systems, of which the detector is based on one of the mentioned sensor principles. This course is open for TM, MBE, APH, NANO and EE students. General knowledge from your bachelor programs is required. For TM students, this course bridges the gap between biophysiology and biomedical signal processing and -analysis. This course consists of 12 lectures, where you actively participate in discussions to reach the learning objectives.. You will write your critical review paper in teams of two students to train and improve your knowledge and understanding via the original papers you have to review. Moreover, a 4-hr practical project concerning synchronous sensor data retrieval into a computer is one of the instructional modes of this course.

Course Contents:Importance of sensing; Specifications of sensors; Electrode-liquid interface; Electrochemical sensing; potentiometry, amperometry, conductometry; Some other biosensors including optical ones;; Electrical signal conditioning with OpAmps; Bioelectricity; Physical sensor principles; Blood flow and pressure sensors; Sensing at the Respiratory System.  

Determining pass mark:Assessment by a written exam counting for 65 % of the final mark, and writing of a critical review paper (remaining 30%). Both parts must be sufficient ( >= 5,5 ). Remaining 5% for the practical project. Only the failed part has to be redone. As the written exam is an open-book exam, conceptual knowledge and understanding is tested. Notwithstanding, problem solving is part of the questions. Obtainable points per part of every question are indicated on the written exam itself. The written exam consists of several open questions with sub-questions. The review paper is requested to be critical, i.e., it should contain original conclusions based on the reviewed papers, and thus being more than a mere summary of the reviewed papers.
