Development of a nanostructured electrochemical immunosensor applied to the early detection of invasive aspergillosis

10.1016/j.microc.2018.03.025

2018-03-16

The use of a biological marker as an adjunct for screening for invasive aspergillosis (IA) in high-risk patients is attractive, because it is noninvasive and may detect evidence of IA prior to the appearance of clinical signs and symptoms. Galactomannan (GMN)...

Continuous monitoring of pH level in flow aqueous system by using liquid crystal-based sensor device
