Abstract
Titanium dioxide (TiO 2 ) is increasingly being used in biosensing applications.
Herein, we review the most recent developments in photoelectrochemical (PEC)
and electrochemiluminescent (ECL) biosensing based on TiO 2 nanomaterials, as
well as the mechanisms that lead to the improved performance of biosensors that
incorporate these nanomaterials. The merits of TiO 2 -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.

1 Introduction
Photoelectrochemical biosensing is promising novel detection method that focuses
on photoelectron transfer processes at biomodified electrode/solution interfaces.
The resulting photocurrent reflects the production of an electron donor/acceptor in
