Recent advances in the development of electrochemical hydrogen peroxide carbon nanotube–based (bio)sensors

Abstract The relevance of H 2 O 2 as biomarker for different neurodegenerative diseases and cancer has been one of the most significant incentives for the development of new (bio)sensors that allow a more sensitive, selective, fast, and stable quantification of H 2 O 2 . In this regard, the association of carbon nanotubes with hemoproteins, nanoparticles, and other nanostructures and different electrochemical transducers has offered new avenues for the construction of innovative H 2 O 2 bioanalytical platforms. This short review highlights the most relevant contributions in the field of electrochemical (bio)sensors for H 2 O 2 based on carbon nanotubes published in the period 2016–2018.
