5Optical, Electrochemical, and Magnetic DNA Biosensors – An

Abstract — This review paper introduces DNA biosensor technology as it is applied to DNA sequencing, mutation sensing, and hybridization sensing. Following this classification, concrete examples of state-of-the-art DNA biosensors are introduced and reviewed as they apply to each of the three areas of DNA sensors. I. INTRODUCTION TO DNA SENSORS The field of biosensors has enlarged greatly over the past few decades through a multitude of technological discoveries and the introduction of new methodologies. Within this broad biosensor field, the sensing of deoxyribonucleic acid (DNA
