Chapter 20: Nanomaterial-based Sensors for Volatile Biomarkers Check Access

This chapter provides an overview of the present and ongoing developments in the field of volatile organic compound (VOC) nanomaterial-based sensors that have been finding use in healthcare. It starts by briefly explaining the advantage of nanomaterials for sensing applications and reviewing the available and quickly progressing VOC sensing devices. There is a discussion of the main trends in material design with special attention given to nanostructuring and nanohybridization, while highlighting emerging sensing materials and strategies. An insightful summary of the field and suggestions of multiple worthy directions in which to choose nanomaterial-based sensors are discussed, while considering the profile of the targeted VOCs and the possible limitations of applying sensing approaches. The perspectives when taking VOC sensors to a new level in the field of diagnostics are made evident.
