ABSTRACT
Heart failure is a chronic condition that sorely affects the worldwide population withhugehealthandeconomic costs. The purpose of this research istopresentanISFET-based immunosensor sensible to low concentrations of TNF-α biomarker in saliva, a protein related with the severity state of heart failure patients,togetherwithaproof-of-conceptIoT-based user-centered health ecosystem, aiming to reduce hospital-centered associated costs and improving patient monitoring. The immunosensor presents a low limit ofdetection of 5pg/mL, with good cross-selectivity versus other saliva biomarkers, using a low cost and short run-time detection technique, optimal for its implementation in a distributed monitoring system.
