Quantum Sensing for Drug Efficacy

Quantum Sensing for Real-Time Monitoring of Drug Efficacy in Synovial Fluid from Arthritis Patients

Nano Lett (2023)

The study explores using diamond-based T1 relaxometry to measure free radical levels in arthritis patients. It differentiates between osteoarthritis (OA) and rheumatoid arthritis (RA) by analyzing synovial fluid and cells treated with the drug piroxicam. The findings indicate a significant reduction in free radicals in OA patients but not in RA patients after treatment, suggesting a potential reason why piroxicam is more effective for OA than RA.
