spintrappingteknologiat
Spintrappingteknologiat refers to a set of analytical techniques used to detect and characterize short‑lived free radicals in chemical, biological, and materials systems. The core principle involves adding a spin trap, typically a nitroxide, nitrone, or nitroso compound, to a sample. When a reactive radical encounters the spin trap, it forms a stable radical adduct that persists long enough to be observed by electron paramagnetic resonance (EPR) spectroscopy. This conversion fixes the radical’s structure into a spectrally identifiable signal, enabling both qualitative and quantitative analysis.
The history of spin trapping dates to the 1960s, when the first spin traps were developed for
Modern spin traps have improved selectivity and stability, allowing in situ monitoring of radicals within living
Because the technique relies on irreversible adduct formation, careful calibration and control experiments are essential to
