ELEC6210 Biosensors

Module Overview

Biosensors combine the typical advantages of electronics and optics (high speed, micro/nanoscale fabrication, etc) with the unique recognition properties of biomolecules, which can electively bind their target molecule even at a high background concentration of similar molecules. A generic biosensor consists of a transducer and a biomolecular interface: the analytes bind to the interface and the transducer transmits this binding event, for example as an electrical signal. ELEC6210 starts with a brief recap of biomolecular structure and function and then proceeds with explaining how biomolecules can be attached to typical transducer materials. Subsequently, the working mechanism of the most common transducers is addressed in detail. The lectures will touch on the commercial criteria for a successful biosensor, for example for point-of-care diagnostic applications. The practical work takes places in the Centre for Hybrid Biodevices (aka the bioECS lab). You will first measure the amount of glucose in various samples with an enzymatic assay using a state-of-the-art UV-VIS photospectrometer and subsequently with commercial amperometric glucose sensors. The last weeks will be dedicated to analysis of specific papers from the scientific literature. In these tutorial sessions we will discuss key points of pre-selected journal papers with the entire group. Note that ELEC6205 Bionanotechnology (semester 1) *or* ELEC3223 Introduction to Bionanotechnology (semester 1) is a prerequisite for this module because ELEC6210 builds on biophysical and biochemical concepts introduced in ELEC6205/ELEC3223.
