Advances in Nanostructured Polyamide-Based Chemical Sensors

Abstract

Nanofibers have shown great potential to contribute to the growing demand for point of care sensors and other kinds of sensors where they are utilized as supporting materials or used to interact with other materials through their functional groups. The choice of a polymer material to be used depends on whether it has the potential to give the properties of the desired sensor. Polyamide nanofibers have properties such as good chemical resistance, very good strength and hardness, high wear resistance, and high surface area to volume ratio, and they are porous, just to name a few. Furthermore, the amide groups in polyamide enable it to interact with other molecules via hydrogen bonding. These characteristics make polyamide nanofibers good candidates for sensor development. Polyamide nanofibers are used nowadays to make various types of sensors. This paper provides a review of some of the reports on the development of nanostructured polyamide-based chemical sensors in the last two decades (2000-2020).
