Titanium dioxide – Based sensors: A review

Titanium dioxide (TiO2) is an electrically conductive material with low electromagnetic waves absorption within the visible range of wavelengths. it has some positive properties allowing it to be implemented in several applications. Here, based on earlier studies, aspects of material selections and applications for TiO2 in the sensors field are mentioned, referenced are given for detailed information. As TiO2 nanomaterials are of great importance for sensor development, COD sensors, gas sensors, and biosensors are discussed with preparations and specifications. For completion improvements and novel works are suggested for each of the discussed sensors.
