NE_2014_08 Who knew that diamonds were useful for more than just engagement rings? Our group is fabricating a DNA biosensor using aptamers (single stranded DNA) functionalized to a diamond surface, rich with nitrogen vacancy centres for detecting small molecules. The device can optically detect magnetic field changes in the nitrogen vacancy centres of the diamond brought on by the presence of the target molecule. The biosensor features both high sensitivity and specificity towards the target, and is capable of providing an instantaneous detection signal in a unique compact design.
