Research Progress of SERS Sensors Based on Hydrogen Peroxide and Related Substances

AbstractHydrogen peroxide (H2O2) has an important role in living organisms, and its detection is of great importance in medical, chemical, and food safety applications. This review provides a comparison of different types of Surface-enhanced Raman scattering (SERS) sensors for H2O2 and related substances with respect to their detection limits, which are of interest due to high sensitivity compared to conventional sensors. According to the latest research report, this review focuses on the sensing mechanism of different sensors and summarizes the linear range, detection limits, and cellular applications of new SERS sensors, and discusses the limitations in vivo and future prospects of SERS technology for the detection of H2O2.Keywords: Hydrogen peroxide (H2O2)intracellular sensorsnanozymesurface-enhanced Raman scattering Authors’ contributionsRuan Shuyan: article writing; Liu Wenting: article collection; Wang Wenxi: literature classification and collation; Lu Yudong: resources.Disclosure statementWe declare that we have no financial or personal relationships with other people or organizations.Table 5.
