Course Objectives : To provide a broad introduction to biological macromolecules as recognition elements, biosensors and their classification. To give an overall view on basic
tools employed in biophysical methods, biomolecular technology and integrating electronic signal transducers. Studies pertaining how engineering and biological approaches can be combined to solve problems in diagnosis of diseases, such as diabetes, cancer or detection of other analytes/biomarkers – emphasizing integration of biological macromolecules (DNA, enzymes, and antibodies) and methodologies for the development of biosensors. Emphasis will also be given to molecular mechanisms underlying cellular processes and
their integration with electronic transducers for biosensor applications.
 
Prerequisite : Any of the interdisciplinary areas covering – Biology, Computer Science,
Materials Science, Chemistry and Electronics
Grading Policy : Midterm 1‐25%  Midterm 2‐25% Final‐ 35% Homework/Seminar – 15%
