Nergiz Sahin Solmaz, PhD candidate at LMIS1, recently participated to “The 55th Annual International Meeting of the ESR Spectroscopy Group of the Royal Society of Chemistry” presenting our recent work concerning the realization of a high-frequency DNP microchip for enhanced ESR spectroscopy.

Nergiz Sahin Solmaz, PhD candidate at LMIS1, presented a poster at “The 55th Annual International Meeting of the ESR Spectroscopy Group of the Royal Society of Chemistry” which has been held in St. Andrews, UK, between June 6-10. It is an academic and international conference pertaining to the advancements of electron spin resonance (ESR or EPR), with an emphasis on methods development, but also including applications and instrumentation innovations.

She presented our latest work “175 GHz ESR Detector for Single-Chip DNP”. The integration of the sensitivity relevant part of electron spin resonance (ESR) and nuclear magnetic resonance (NMR) detectors are a promising approach to improve the limit of detection. Dynamic nuclear polarization (DNP) is a proven concept to enhance the NMR signal amplitude. Previously, a 10 GHz integrated oscillator has been developed as a microwave source for the first single-chip DNP microsystem in our lab. In this poster, we have shown an increase of the frequency of the microwave source more than an order of magnitude. Additionally, ESR signal is acquired utilizing an amplitude detection which reduces the complexity of the high frequency measurements. The microwave signal is generated locally requiring only DC cables.
