19 Sensor100 December 2018 Paper biosensors: towards eco-friendly diagnosis Niamh T Brannelly and Laura Gonzalez-Macia, researchers at OSASEN SENSORES SL. Spain, have written a comprehensive review and argument for the use of paper based bisensors in disease diagnosis. “The area of pa- per-based bio- sensors is in its infancy; thus, a gap remains between the advanced re- search undergone at academia and clinical applications. This is mainly due to challenges such as substrate fragility, mass production, sample preparation and system inte- gration.There are some successful paper-based bio- sensors that have reached the market, such as the pregnancy test. But they mainly provide qualitative or semi-quantitative yes/no responses, limiting its range of application” say the authors. Reported by EuroScientist 10 December WSU researchers create 3D-printed glucose biosensors A 3D-printed glucose biosensor for use in wearable monitors has been created byWashington State University researchers. Using 3D printing, theWSU research team developed a glucose monitor with much better stability and sensitivity than those manufactured through traditional methods. The sensor appears to be some way from real use on patients, and it is not clear if it measures glucose in sweat, which does not correlate with plasma glucose.
