Abstract	The first demonstration of a pulsed electron paramagnetic resonance (EPR) detection system based on the recently announced particle EPR (pEPR) technology for superparamagnetic iron oxide nanoparticles (SPIONs) applications is presented. The SPIONs have large magnetisation, which allows one to detect the electron resonance under a low magnetic field and at room temperature. However, the broad linewidth of the superparamagnetic particles leads to a short relaxation time which requires a quick damping of the transmit signal. The presented experiments on a commercial SPION prove the feasibility to detect a pulsed electron response from broad linewidth particles using the pulsed pEPR technology.
