Biosensors for disease biomarker detection

This chapter describes the current and emerging biosensor technologies for detection of biological markers (biomarkers) associated with disease. The chapter first reviews disease biomarkers and their use, as well as the established technologies for disease biomarker detection. The chapter then discusses the issues with non~specific adsorption of proteins at surfaces and presents solutions to overcome these issues. Finally, the emerging biosensor technologies for disease biomarker detection are described.
