Microfluidics-Based Biosensors: A Microfluidic Paper-Based Origami Nanobiosensor for Label-Free, Ultrasensitive Immunoassays (Adv. Healthcare Mater. 11/2016).
The first microfluidic paper-based origami nano-biosensor featuring zinc oxide nanowires and an electrochemical impedance spectroscopy biosensing mechanism, for label-free, ultrasensitive immunoassays is reported by X. Li and X. Liu on page 1326. The sensor consists of cellulose paper, a carbon ink electrode, and zinc oxide nanowires directly grown on the top. Possible parallelization of assays and high storage stability render the sensor promising for clinical diagnostics applications.
