India, Feb. 24 -- Researchers at CEA-Leti and CEA-IRIG-SyMMES have validated a chip-scale electron paramagnetic resonance (EPR) spectrometer that achieves unprecedented scan speed, spectral span, and sensitivity from a battery-operated integrated circuit.

By replacing the bulky electromagnets used in conventional EPR instruments with an ultra-fast frequency-scanned architecture, the system enables high-performance paramagnetic sensing in portable and space-constrained environments where traditional systems cannot operate.

SyMMES, the Molecular Systems and (Nano)Materials for Energy and Health Laboratory, is one of IRIG's joint research units (UMR 5819). It brings together staff from CEA, the French National Centre for Scientific Researc...
