Abstract
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.
