Paper Based Point of Need (PON) Spectro-electrochemical Smartphone Based Sensors for Citizen Chemical Sensing Analytics
Abstract
Our research group is focused on developing printed paper-based point of need (PON) colorimetric and electrochemical sensors for real-time wireless monitoring of water and soil nutrients for precision agriculture, as well as stress metabolites sweat analytics for mental health assessment in humans. Fabricated by layer by layer (LbL) integration of analyte selective biomimetic molecular receptors and transduction on a smartphone, in this presentation we will demonstrate our multi-architecture sensors for in-situ multiplex colorimetric and electrochemical detection of soil quality indicators namely, redox potential, pH, cation exchange, phosphates and nitrites; as well as lactic acid, adrenaline, cortisol, and adrenaline, detection in human sweat. Our embedded multiplex sensors are aimed to be enabling proactive diagnostics technology for realization of environmental, social, and economic aspects that align with the United Nation’s Sustainable Development Goals (UN SGDs), particularly sustainable smart agriculture, climate change, food security, environmental conservation, and in general, equity in global societies wellbeing.
