Sensors and biosensors based on metal oxide nanomaterials

Nanomaterials have greatly boosted the biosensor field taking advantage of their optical, catalytic, magnetic and adsorption properties. While noble metal and carbon-based materials have been most often used, metal oxide nanomaterials (MONMs) have recently emerged as a useful platform for their high stability, low cost and versatility in chemical properties. In this article, we first introduce fundamental surface properties of MONMs, especially...
