Reactive strategy-based SERS determination of O2˙- generated from sunscreen.

Published in: Chemical communications (Cambridge, England) (2021)

A novel surface-enhanced Raman scattering (SERS) nanoprobe based on a reactive strategy was designed for the first time to determine the concentration of superoxide anion radical (O2˙-) produced from titanium dioxide by a UV radiation process. A limit of detection (LOD) for O2˙- of 9.0 nmol L-1 could be attained.
