Diamond-based Sensors and Biolabels for Biomedical Applications

For several decades, diamond has emerged as a prominent member of the carbon, owing to its exceptional biocompatibility and non-bleaching properties. As a result, significant advancements and groundbreaking discoveries have been made in the fields of biomedical imaging, nanoscale magnetic sensors, surface modification, and biomedical applications. Notably, the nitrogen-vacancy center, a defect in diamond, plays a crucial role as a quantum sensor, enabling sensitive detection of paramagnetic species. This thesis focuses primarily on using diamonds to study other materials or biological samples and carries out preliminary investigations to uncover their potential.
