Arben Merkoҫi (Ed.): Paper based sensors.

The following fourth and fifth chapters are devoted to paper-based electrochemical devices, including interesting and new points of view such as the role of paper in electroanalytical devices with special emphasis on its use as reactor as well as on the employ of different electrochemical techniques (amperometric, voltammetric, impedimetric or potentiometric), on the development of lateral and vertical flow paper-based microfluidic devices or on the detection in liquid and gas phases. The first chapter explores paper as a substrate for electrochemical micro-devices, being this principle of detection the most promising in the (bio)sensor field. The following three chapters (nineth, tenth and eleventh) are more specific, related to nanopaper-based (optical and electrical) sensors, nanoparticle-based lateral flow assays, and flexible cellulose-based devices for monitoring physical parameters.
