Determination of dihydralazine based on chemiluminescence resonance energy transfer of hollow carbon nanodots

The CL of KMnO4-HSO3− was enhanced by HCNs. The enhanced mechanism CL was induced by HCNs⁎, which produced from the electron-transfer annihilation and CRET. The competitive consumption of O2- by DHZS inhibited CL intensity. The method was applied to the determination of DHZS in pharmaceutical preparations and human fluid samples.157
