Multifarious aspects of electrochemical paper-based (bio)sensors
Abstract
Abstract In the last decade, electrochemical paper-based (bio)sensors have garnered much attention in the sensing field thanks to their cost-effectiveness, easiness to use, and miniaturisation. Besides these characteristics in common with the other electrochemical (bio)sensors, the features of paper such as foldability and porosity have opened new unprecedented electrochemical (bio)sensor configurations allowing for reagent-free measurements, origami-like set-up, and the absence of sample treatment. In addition, after the measure, the device can be burned reducing the waste management with relevant decrease of cost analysis in case of biological fluids or warfare agents. Herein, we report how we have exploited the features of paper to design smart biosensors able to treat the sample, to contain any reagent needed for the measurement, and to make the measurement delivering novel paper-based lab-on-a-chip devices.
