Postgraduate Course: BioSensors and Instrumentation (PGEE11040)
|School||School of Engineering
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 11 (Postgraduate)
||Availability||Not available to visiting students
|Summary||The Biosensors and Instrumentation course examines the methods used to interface sensors for biological and biomedical applications with electronics. One focus will be on transducers, meaning devices which convert information from one form of energy to another. In this case the final form for the information will be an electrical signal but the transducers themselves could be optical, mechanical, etc., and operate in a number of different ways (eg., capacitive, potentiometric, photonic). The objective is to build upon the knowledge the students will have gained in the introductory courses in semester 1 on bioelectronics and biosensors but with more of an electronics and electrical engineering focus. This course will also go beyond sensing to look at methods of actuation for closed loop "smart" systems. Examples from the state of the art in biosensor research will be provided and a number of guest lectures from active researchers in this field will provide context. Students will undertake a "horizon scanning" research exercise to investigate the industrial and research potential of a specific type of biosensor. This will be assessed by both formal reports and a presentation given to and marked by the whole class.
There are two lectures each week. The main body of the course will run from weeks 1-10 with the lecture slots taken up with coursework presentations in week 11. 2-3 guest lectures are planned during the semester with timings to be determined. These will cover active research in the field of biosensing and in previous years have looked at: "cantilever based biosensors", "advanced photodetector arrays" and "electrical cell impedance sensing".
The following subjects will be covered during the course, Most of these will take more than one lecture slot:
L1. Transducer Basics: Sensors and Actuators
L2. Sensor Amplification: Op-amps, basic circuits
L3. Instrumentation for Electrochemistry: Potentiostats, impedance measurements, bridge circuits
L4. Temperature measurements
L5. Mechanical sensor instrumentation: Strain gauges, piezoelectric sensors and actuators, capacitive sensor interfaces
L6. FET based sensors: MOSFET revision, FET based biosensors, nano-wire sensors.
L7. Overview of optical biosensors: Fibre-optic sensors, fluorescence
L8. Neural sensors and actuators: Microelectrode arrays, neural implants
L9. Implantable medical devices: Biofouling, materials and regulation
L10. Wireless sensor interfaces: Sensor networks and wireless power
