Nano-Enriched and Autonomous Sensing Framework for Dissolved Oxygen

Sensors (Basel). 2015 Aug 14;15(8):20193-203. doi: 10.3390/s150820193.

Abstract

This paper investigates a nano-enhanced wireless sensing framework for dissolved oxygen (DO). The system integrates a nanosensor that employs cerium oxide (ceria) nanoparticles to monitor the concentration of DO in aqueous media via optical fluorescence quenching. We propose a comprehensive sensing framework with the nanosensor equipped with a digital interface where the sensor output is digitized and dispatched wirelessly to a trustworthy data collection and analysis framework for consolidation and information extraction. The proposed system collects and processes the sensor readings to provide clear indications about the current or the anticipated dissolved oxygen levels in the aqueous media.

Keywords: ceria nanoparticles; data collection; oxygen sensing; sensing framework.
