Abstract

Magnetic resonance measurements of ferumoxytol and TEMPO were made using an on-wafer transmission line technique with a vector network analyzer, allowing for broadband measurements of small sample volumes (4 nl) and a small numbers of spin (1 nmole). On-wafer resonance measurements were compared with standard single-frequency cavity based electron paramagnetic resonance (EPR) measurements; and results showed similar line shapes. On-wafer magnetic resonance using integrated microfluidics and microwave technology can significantly reduce cost and sample volumes required for EPR spectral analysis and allow for integration of EPR with existing lab-on-a-chip processing and characterization techniques for point-of-care medical diagnostic applications.
