This project aims to develop molecular quantum sensors—nanoscale probes that use optical detection of spin states to sense biochemical changes with exceptional sensitivity. Unlike solid-state NV centres in diamond, molecular sensors offer flexibility through synthetic chemistry and easy integration into biological environments via bioconjugation techniques such as click chemistry.
Key aspects:
- Research focus: Optical spin readout in biologically compatible molecules for detecting temperature and biochemical changes at the single-molecule level.
- Advantages: Molecular systems allow tailored control over coherence time, spin-optical contrast, and sensing performance.
- Approach: Build on recent breakthroughs in optical spin readout and coherent spin control in chemically synthesised molecules.
- Skills developed: Quantum sensing, spectroscopy, spin resonance, and quantum-mechanical simulations.
- Impact: Opens new routes for quantum-enhanced biosensing and medical diagnostics.
