Abstract
Titanium dioxide (TiO2) is increasingly being used in biosensing applications. Herein, we review the most recent developments in photoelectrochemical (PEC) and electrochemiluminescent (ECL) biosensing based on TiO2 nanomaterials, as well as the mechanisms that lead to the improved performance of biosensors that incorporate these nanomaterials. The merits of TiO2-based ECL and PEC biosensing strategies are summarized by highlighting some illustrative examples that have been reported within the last 5 years. The future prospects for and challenges in this field are also discussed.
