Nanoparticles for sensing of reactive oxygen species and reactive oxygen species sensing method using the same

摘要

The present invention relates to a nanoparticle for sensing activated oxygen, comprising a gold nanoparticle, polyethylene glycol (PEG) attached to the surface of the gold nanoparticle, and a fluorescent substance attached to the polyethylene glycol; and to a method for quantitatively sensing activated oxygen using the same, which allows the selective quantitative measurement of only activated oxygen generated by the gold nanoparticle.
