A microfluidic cell 40 comprising a microfluidic channel (32, Fig. 3) for receiving a fluid sample; and a sensor 42, adjacent the channel, comprising a diamond material with one or more quantum spin defects 46 (e.g. nitrogen-vacancy (NV) defects). The â lab-on-a-chipâ cell may be mounted in the cell receiving bay of a spin resonance device which further comprises variable oscillating field generators for manipulating quantum spins within the fluid sample and the quantum spin defects in the sensor respectively; a light source 44 for optically pumping the quantum spin defects in the sensor; and a detector 48 for detecting emission from decaying quantum spin defects. The resultant data may be NMR or ESR (nuclear magnetic or electron spin resonance) data - e.g. an NMR spectrum indicating chemical shift information or a magnetic resonance image. |
