An 8-channel 13GHz ESR-on-a-Chip injection-locked vco-array achieving 200μM-concentration sensitivity

Abstract

Thanks to their unmatched specificity, methods based on magnetic resonance effects are amongst the most powerful spectroscopic techniques available today. Out of these methods, due to the availability of improved electronics at the required frequencies in the tens of GHz region, electron spin resonance (ESR) spectroscopy is gaining significant attention in the research community as a tool in life science and materials science research.
