Abstract
Methods based on the nuclear magnetic resonance (NMR), electron spin resonance (ESR), and ferromagnetic resonance (FMR) phenomena are powerful, non-invasive, and widely employed tools which allowed major advances in physics, material science, chemistry, biology, and medicine. The importance of magnetic resonance methods is recognized in disciplines such as the determination of the structure of complex molecules, metabolomics, catalysis, in-vivo tumors detection, functional studies of the brain, process control/optimization, and quantum computing.
The use of magnetic resonance methodologies in an even wider range of applications is often hindered by the relatively large concentrations and minimum number of resonating spins needed to achieve a sufficiently large signal-to-noise ratio in the available experimental time. Experiments at the nanoliter and subnanoliter scale requires detectors and methods which are significantly different from those commercially available and used to perform experiments on microliter and larger volumes. At the nanoliter and subnanoliter scale, both inductive and non-inductive (e.g., optical and mechanical) detection methods are currently investigated.
In this seminar, after an introduction to the physics and state-of-the-art of nanoliter and subnanoliter magnetic resonance, I will focus on my research activities on the inductive detection of NMR and ESR using single chip integrated sensors and on the X-ray detection of FMR using synchrotron radiation beamlines.

Short biography
Giovanni Boero received his diploma in physics from the University of Genova (Genova, Italy) in 1994. From 1994 to 1996 he worked on clusterized gas beams for particle physics experiments at FERMILAB (USA) and at CERN (Switzerland). Since 1996, he is working at EPFL (Switzerland), where he obtained the PhD degree in 2000 and the title of Senior scientist in 2012. His research interests are in the field of nuclear magnetic resonance (NMR), electron spin resonance (ESR), and ferromagnetic resonance (FMR) spectroscopy of at the nanoliter and subnanoliter scale, low noise RF and microwave integrated electronics, and magnetic sensors.
