This project aims to pioneer quantum sensors based on individual spins in luminescent molecules, creating a new class of nanoscale probes for detecting magnetic fields, temperature, strain, and electric fields with unprecedented sensitivity. Unlike solid-state defect spins (e.g., NV centres in diamond), molecular spins offer tunability, nanoscale modularity, and versatility through chemical synthesis and functionalisation.
Key aspects:
- Objectives:
- Demonstrate measurement and control of single molecular spins.
- Explore chemical tunability to enhance quantum-sensing performance.
- Develop application-specific molecular platforms for biomedicine and materials science.
- Methods:
- Optically detected electron spin resonance.
- Time-correlated single-photon counting.
- Cryogenic scanning confocal microscopy, complemented by simulations.
- Impact: Opens new routes for quantum-enhanced sensing in biology and materials science, leveraging molecular-level engineering for proximity and specificity.
- Environment: Work within the Quantum Optospintronics Group at the University of Glasgow, with access to state-of-the-art facilities and strong national/international collaborations.
