Periodic Reporting for period 2 - PETER (Plasmon Enhanced Terahertz Electron Paramagnetic Resonance)

Berichtszeitraum: 2019-01-01 bis 2021-06-30

Zusammenfassung vom Kontext und den Gesamtzielen des Projekts

Electron paramagnetic resonance (EPR) is a powerful technique finding its applications in many scientific areas covering chemistry, biology, medicine, materials science, physics and others. EPR has an unprecedented selectivity but relatively low sensitivity compared to other spectroscopic techniques, which makes EPR (working in the microwave spectral region) impractical for low-spin-density materials, especially when the imaging mode for heterogeneous samples is needed. In the project we propose a qualitatively new approach into the EPR area. It builds upon the strong enhancement and subwavelength spatial resolution of magnetic sensing field provided by plasmonic effects based on collective oscillations of electrons at surfaces or in nanostructures. In contrast to usual THz plasmon-enhanced spectroscopy of nonmagnetic materials, we build upon magnetic plasmonic resonances. This presents unprecedented implementation of plasmonic phenomena into EPR technique. Plasmon-enhanced Terahertz Electron Paramagnetic Resonance (PE THz EPR) spectroscopy and scanning microscopy is developed as a radically novel method for the local analysis of paramagnetic organic and inorganic species and materials with significantly enhanced sensitivity (by four orders of magnitude) and unprecedented spatial resolution. Such a significant enhancement of the EPR performance will for instance open new ways in magnetic sensing technologies enabling to study in situ functional centres in a wide variety of materials, and, generally, trigger the development of the EPR-employing industry.

Arbeit, die ab Beginn des Projekts bis zum Ende des durch den Bericht erfassten Berichtszeitraums geleistet wurde, und die wichtigsten bis dahin erzielten Ergebnisse

The project generated the following outputs:
- WP1 deliverables on PE EPR spectroscopy (concept, design and fabrication of plasmonic structures, proof-of-concept samples for PETER)
- WP2 deliverables on PE EPR microscopy (concept, design and demonstrator of SPM unit, cantilever tips and platform for PE EPR microscopy)
- WP3 deliverables (Visual Identity, Quality Plan, Data Management Plan, Communication and Dissemination Plan and its updates, Scientific Communication and ORDP)
- Summer school on EPR, plasmonics and THz techniques at CEITEC Brno
- 2 workshops for the scientific community (2019, Austria and 2021,online) and participation to workshops for industry
- publications and other dissemination outputs available at https://www.peter-instruments.eu/section/scientific-output/

Fortschritte, die über den aktuellen Stand der Technik hinausgehen und voraussichtliche potenzielle Auswirkungen (einschließlich der bis dato erzielten sozioökonomischen Auswirkungen und weiter gefassten gesellschaftlichen Auswirkungen des Projekts)

This project is of a foundational nature as it establishes a basis for a new line of technology currently not anticipated. We will transform EPR spectroscopy from a niche technique to one that is ubiquitously present in science and society, opening a new dimension in materials research and in healthcare, security and energy storage, revolutionizing other areas where plasmonics and imaging are combined, and generating a research field of its own in EPR imaging.
