Introduction by Gemma Gabriel (GAB).
Abstract
Chemical sensors and biosensors, considered as compact analytical devices, are highly attractive due to their ease of use, fast response, small size, and the possibility of continuous monitoring, among other reasons. The scientific community of chemical sensors and biosensors dedicates a sustained effort in order to improve the quality and reliability of these devices, seeking to achieve better figures of merit, such as sensitivity, detection limit, stability and reproducibility. In this sense, the properties of nanomaterials can provide improved characteristics to the sensors. This presentation will introduce some approaches carried out in the framework of collaborations with our group in which nanomaterials were incorporated into sensors and biosensors in order to fulfill certain specific functions, such as serving as a substrate for the immobilization of biomolecules, allowing selective passage of certain compounds to an electrode, and acting as conductive matrices in electrochemical sensors or as catalysts for redox reactions in printed sensors.
